ABCD is a quadrilateral such that the measures of three of its interior angles are given as B=122 degrees, C= 75 degrees, D= 51 degrees, find m=A
please help me with explanation
Answer:
angle A is 112 degree.
Step-by-step explanation:
quadilateral have 4 angles .
sum of the interior angles of a quadilateral is 360 degree
Here,
angle A = be x
angle B = 122
angle C = 75
angle D = 51
Now,
angle A + angle B + angle C + angle D =360 degree
x + 122 + 75 + 51 = 360
x + 248 = 360
x = 360 - 248
x = 112

Answer: x=-3
Step-by-step explanation:
First let's eliminate the square root
[tex](\sqrt{x^2-5x+2})^2=(\sqrt{x^2+17})^2\\x^2-5x+2=x^2+17[/tex]
Now subtract [tex]x^2\\[/tex] from both sides
[tex]x^2-5x+2-x^2=x^2+17-x^2\\-5x+2=17[/tex]
Subtract 2 from both sides
[tex]-5x+2-2=17-2\\-5x=15[/tex]
Finally divide both sides by -5
[tex]\frac{-5x}{-5} =\frac{15}{-5} \\x=-3[/tex]

An angle measures 104° more than the measure of its supplementary angle. What is the measure of each angle?
___° and ___°
thank you <3 best answer will get brainliest.
Mark Brainliest please
Answer:
38 degrees
Step-by-step explanation:
Let the angle be x
Supplement:: 180-x
Equation:
x = 180-x + 104
2x = 284
x = 142 degrees
therefore , 180-x = 180-142= 38 degrees

768, 480, 300, 187.5, …
/
9514 1404 393
Answer:
5/8
Step-by-step explanation:
Since the ratio is common, it can be found from the ratio of any pair of adjacent terms.
r = 480/768 = (5·96)/(8·96) = 5/8
The common ratio is 5/8.
Which pair of expressions below are equivalent?
a. 7(2n) and 9
b. 3n + 5n and 15n
c. 4(2n-6) and 8n - 24
d. 7(2n) and 72n

A club is choosing 2 members to serve on a committee. The club has nominated 3 women and 3 men. Based on chance alone, what is the probability that one woman and one man will be chosen to be on the committee
Answer: 0.6
Step-by-step explanation:
Given
There are 3 women and 3 men available to form a 2 member committee.
No of ways, a man can be chosen are [tex]3[/tex]
Similarly, no of ways a woman can be chosen are 3
Therefore, probability of choosing 2 members i.e. 1 man and 1 women is
[tex]\Rightarrow P=\dfrac{3}{6}\times \dfrac{3}{5}[/tex]
If the order matter, then
[tex]\Rightarrow P=2\times \dfrac{3\times 3}{6\times 5}\\\\\Rightarrow P=0.6[/tex]
The probability that 1 woman and 1 man will be chosen is "0.6".
According to the question, the club has nominated:
Number of women = 3 Number of men = 3Now,
→ The number of ways to select two persons from 6 will be:
= [tex]\binom{6}{2}[/tex]
hence,
The probability that one woman and one man will be chosen will be:
→ [tex]P(1 \ women \ and \ 1 \ women) = \frac{\binom{3}{1} \binom{3}{1}}{\binom{6}{2}}[/tex]
[tex]= 3\times \frac{3}{15}[/tex]
[tex]= \frac{9}{15}[/tex]
[tex]= 0.6[/tex]
Thus the above answer is right.

Laura, David, and Carlos served a total of 115 orders Monday at the school cafeteria. David served 3 times as many orders as Carlos. Laura served 10 more orders than Carlos. How many orders did they each serve?
Answer:
Step-by-step explanation: ts 6 11 19 56
Laura, David, and Carlos served a total of 115 orders
David served 3 times as many orders as Carlos. David = 3x
Laura served 10 more orders than Carlos. let Carlos = x
How many orders did they each serve? Laura = x + 10
Carlos + David + Laura = 115
x + 3x + x+10 = 115
5x + 10 = 115
5x = 115 - 10
5x = 105
x = 21 Carlos
63 Davide
31 Laura
add then up 115 Total

Use the concept of a series to sum up 0.315+0.000315+0.000000315+.... Give your final answer
in reduced fraction form. Note: There are several methods to prove this fact. I am specifically asking
you to use a series.
Dividing each term in the given series by 0.315 reveals a simple geometric sum,
0.315 (1 + 1/1,000 + 1/1,000,000 + …)
or
0.315 (1 + 1/10³ + 1/10⁶ + …)
or
[tex]\displaystyle 0.315 \sum_{n=0}^\infty \frac1{10^{3n}} = 0.315 \sum_{n=0}^\infty \frac1{1000^n}[/tex]
i.e. a geometric sum with a common ratio of 1/1,000. I'm not sure what your instructor expects exactly, but you may already know that
[tex]\displaystyle a\sum_{n=0}^\infty r^n = \frac a{1-r}[/tex]
if |r | < 1. This is the case here, so
0.315 (1 + 1/1,000 + 1/1,000,000 + …) = 0.315 / (1 - 1/1,000)
… = (315/1000) / (999/1000)
… = 315/999
… = 35/111
