Answer:
x=6
Step-by-step explanation:
We can use ratios to solve
18 4x+6
--------- = -------------
24 40
Using cross products to solve
18*40 = 24 * (4x+6)
720 = 24*(4x+6)
Divide each side by 24
720/24 = 24/24 (4x+6)
30 = 4x+6
Subtract 6 from each side
30-6 = 4x+6-6
24 = 4x
Divide each side by 4
24/4 = 4x/4
6 = x

Can adjacent angles be complementary?
Give a brief explanation as to why or why not.
Answer:
Yes, adjacent angles can be complementary. Complementary angles are defined as two acute angles with a sum that is equal to 90°. if they add up to 90°. For example, a diagonal of a square will split the right angle into two equal angles; 45°+45°. In a right triangle, the altitude from a right angled vertex will split the right angle into two adjacent angles; 30°+60°, 40°+50°, etc. Those adjacent angles are complementary.

Question:
Kira is using the figure shown to prove the Pythagorean theorem. She starts by writing the
equation [tex](a+b)^2 - c^2 = 4(\frac{1}{2}ab )[/tex] because she knows two equal ways to represent the area
of the shaded region. Which best describes the next steps Kira should take to complete her
proof?
Answer:
The correct option is;
d. Simplify both sides of the equation to get a² + 2·a·b + b² - c² = 2·a·b then subtract 2·a·b and add c² to both sides of the equation
Step-by-step explanation:
Here we have
The area of the larger square = (a + b)²
The area of the middle plain shaded square = c²
∴ Area of the shaded region = (a + b)² - c²
The shaded region consists of for right triangles of base, a and height, b therefore, the area of the shaded region is also the area of the four right triangles = 4 × (1/2 × base × height)
= 4×1/2×a×b = 4(1/2·a·b)
Hence area of the shaded region also = 4(1/2·a·b)
Therefore, (a + b)² - c² = 4(1/2·a·b)
Which is a² + 2·a·b + b² - c² = 4 × 1/2 × a·b = 2·a·b
∴ a² + 2·a·b + b² - c² = 2·a·b
Hence a² + 2·a·b + b² - c² + c² = 2·a·b + c² gives
a² + 2·a·b + b² = 2·a·b + c² gives
Also a² + 2·a·b + b² - 2·a·b = 2·a·b + c² - 2·a·b gives
a² + b² = c² which is Pythagoras theorem

The correct question is;
You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent. If necessary round your answer to the nearest hundredth. Find the probability of spinning an odd number, flipping heads, then spinning another odd number? Write your answer as a fraction in simplest form.
Answer:
If the spinner has an even number of spaces, the probability of spinning an odd number, flipping heads, then spinning a yellow is = 1/8
Whereas, if the spinner has an odd number of spaces, more information is needed
Step-by-step explanation:
The answer will depend on whether the spinner has an odd or even number of spaces.
Now, if we suppose that the spinner has an even amount of numbers on it, there will be an equal number of odd and even numbers.
Thus the probability of spinning an odd number is ½.
Also, the probability of flipping heads on a coin is ½.
Thus, the probability of spinning an odd number, flipping heads, then spinning another odd number is;
= ½ × ½ × ½ = ⅛
Similarly,
If the spinner has an odd amount of numbers on it, the probability of spinning an odd number will vary. For instance, if there are 5 spaces on the spinner, the probability of spinning an odd number will be
3
However, if there are 9 spaces, the probability will be 5/9
So,we can conclude that;
If the spinner has an even number of spaces, the probability of spinning an odd number, flipping heads, then spinning a yellow is = 1/8
Whereas, if the spinner has an odd number of spaces, more information is needed.

The price of a cup of coffee was $2.35 yesterday. Today, the price fell to $2.10. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
10.6% decrease
Step-by-step explanation:
The percentage change in a quantity is computed using ...
percentage change = ((new value)/(old value) -1) × 100%
= (2.10/2.35 -1) × 100%
= (0.8936 -1) × 100%
= -.1064 × 100%
= -10.64%
The percentage decrease was about 10.6%.

How do u find the unknown angle measure in a triangle
Answer:
Use the sum of angle measures rule.
Step-by-step explanation:
If you are given two angles and one missing angle, it's good to remember that all angles add up to 180°.
You can add the the given angles measurements, and subtract them by 180. You should then get the missing angle measure.

Step-by-step explanation:
3(K-2)=15
How do I solve for K
Answer:
7
Step-by-step explanation:
step 1. divide 15 by 3
(K-2)=5
step 2. add the 2 to the 5
K=7
Answer: k = 7
Step-by-step explanation: Start by distributing the 3 through the parentheses on the left side of the equation.
3(k) is 3k and 3(-2) is -6.
So we have 3k - 6 = 15.
Next, isolate the k term by adding 6 to both
sides of the equation and we get 3k = 21.
Now divide both sides by 3 and k = 7.
If you want, you can check your answer by plugging a 7
back into the original equation to see if it works.

Step 2: Radii OK and NL are perpendicular to OM because of the radius-tangent theorem. By definition of perpendicular, angles KOM and LNM are right angles. This means that triangles KOM and LNM are right triangles. Angle LMN is common to both right triangles, so by the _________________________, triangles KOM and LNM are similar. please fill in the blank
Answer:
AAA postulate.Step-by-step explanation:
Givens
Angles KOM and LNM are congruent, because both are right.Angle LNM is common to both triangles.If two internal angles of two triangles are congruent, then the third angle is also congruent.
Therefore, the similarity is proven by AAA postulate, which states that if we have three corresponding angles congruent, then those triangles are similar.
Remember that similarity is about proportion between sides and congruence between angles.

What is t in degrees?
Answer:
100
Step-by-step explanation:
Because the 40 degree angle is an inscribed angle opposite of arc u, arc u's angle measure must be 40*2=80 degrees. Since t+u=180 degrees, t must be 100 degrees. Hope this helps!
