Answer:
B = 42.9°
C = 87.1°
c = 7.4
Step-by-step explanation:
In this problem we are given two sides and one angle of a triangle ABC. The given values are:
a = 9
b = 8
A = 50°
In this case, there wil be only one solution, because the side opposite the given angle (side a) is longer than side b that was also given.
Calculating, let's the the law of sines.
[tex] \frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c} [/tex]
[tex] \frac{sin 50}{9} = \frac{sin B}{8} = \frac{sin C}{c} [/tex]
Taking for A & B, we have:
[tex] \frac{sin 50}{9} = \frac{sin B}{8} [/tex]
Let's cross multiply
(sin 50°)(8) = 9 sinB
Solving further,
[tex]sin B = \frac{8 sin 50}{9}[/tex]
[tex] sin B = \frac{6.128}{9}[/tex]
[tex] B =sin^-^1(0.68)[/tex]
B = 42.9°
Since the total angle of a triangle is 180°, to find C, we have:
C = 180 - 50 - 42.9
C = 87.1°
To find the length of c, let's also use the sine formula.
[tex]\frac{sin B}{b} = \frac{sin C}{c} [/tex]
[tex]\frac{sin 42.9}{8} = \frac{87.1}{c} [/tex]
Cross multiplying
8c = 87.1 sin 42.9
[tex] c = \frac{87.1 sin42.9}{8} [/tex]
c = 7.4
What is this number in standard form?
(7×100)+(4×1100)+(8×11,000)
Answer:
Step-by-step explanation:
factor out 100
100[7 + (4 * 11) + (8 * 110)]
100[7 + 44 + 880]
100 (931)
= 93100
standard form is 9.31 * 10^4
The standard form for the number (7×100)+(4×1100)+(8×11,000) is, 9.31×10⁴
What is the standard form of a number?The standard form for a number is a method by which we write number in a format like b×10ˣ. The value of b should be in between 0 to 10.
Given Number,
⇒ (7×100)+(4×1100)+(8×11,000)
by taking 100 common from all the three terms,
⇒ 100[ 7+ (4×11) + (8×110) ]
⇒ 100[7+44+880]
⇒ 100×931
⇒ 9.31×10⁴
Hence, The number can be written as, 1.39×10⁴

PLEASE HELP...SOLVE FOR VOLUME
Answer:
to get volume you have to do this base x height
Step-by-step explanation:
12 x 8 is 96 that the base
next base times height which is 1996.8 however since the shape is a triangle and not a square you have to divide by 2 so the answer is 998.4 m^2
Answer:
volume = 12* 19.2*8/2 = 921.6 m3
Step-by-step explanation:
20.8^ 2 - 8^ 2 = a^2 = 19.2^ 2
volume = 12* 19.2*8/2 = 921.6

Answer:
[tex]232 cm^{2}[/tex] (B.)
Step-by-step explanation:
Don't overwhelm yourself. Take a deep breath and look at the triangle that has the height of 14 cm.
Recall that the area of a triangle is A= 1/2bh
The base of the triangle is 8 cm, if you eyeball it with the square. The height is given as 14.
1/2 (14)(8)
= 56 cm^2 x 2
= 112 cm^2
Great! We found two of the triangles (there are two of these, look at the paper)
Now let's take a look at the second triangle with the height of 12 cm.
Eyeball the base, which is 6 cm from the square in the middle.
1/2 (6)(12)
= 36 x 2
= 72 cm^2 (there are two of these triangles)
The easy part comes. The area of a square is simply
A= bh
= (6)(8)
= 48 cm^2.
ADD 'EM UP
48 + 72 + 112
= 232 cm^2
Answer:
B) 232
Step-by-step explanation:
Do 14 x 8 to find the top and bottom triangle. 112. Then do 12 x 6 to find the left and right triangle. 72. The find the area of the rectangle 6 x 8 = 48. Add up all the answers. 112 + 72 + 48 = 232 is the answer.
How many triangles exist with the given angle measures?
Answer:
The answer would be one triangle. it is only one triangle because the sum of the angles of any triangle have to equal 180°. So if you add all of the angles you gave us, that would equal 180°.

A. 36 cm
B. 282.6 cm
C. 45
D. 10
Answer:
A. 36.4cm = h
Step-by-step explanation:
A=2πrh+2πr² This is the equation to find the surface area of a cylinder
2532 = 2π(9)h + 2π(9)² Multiply
2532 = 18πh + 2π(81) Multiply
2532 = 56.55h + 162π Multiply
2532 = 56.55h + 508.94
-508.94 - 508.94 Subtract 508.94 from both sides
2023.06 = 56.55h Divide both sides by 56.55

circumference C = 50.2654825 ft
Step-by-step explanation:
Answer:
2 144.7 ft³
Step-by-step explanation:
So the diameter of this sphere is 16ft.
The equation of the volume of a sphere is [tex]\frac{4}{3}[/tex]πr³.
r is the radius which is half of the diameter. So half of 16 is 8.
Now all you have to do is the equation 4 x π x (8)³ divided by 3.
That should equal 2 144.7 ft³

SOLVE FOR VOLUME
Answer:
volume = area of triangle * height = 12.124355653*14/2 * 20 = 1697.40 m3
Step-by-step explanation:
the triangle is equilateral triangle ->
a^2 = 14^2 - 7^2 = 147
-> a = 12.124355653
volume = area of triangle * height = 12.124355653*14/2 * 20 = 1697.40 m3
Answer:
[tex]196meters^2[/tex]
Step-by-step explanation:
The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]
To work this out you would first have to work out the area of the triangle. You can do this by multiplying the base of 14 by the height of 14, this gives you 196.
The next step is to divide the answer of 196 by 2, this gives you 98. This is because the formula is the same as that for the area of a square and that a triangle would be half of a square with the same dimensions.
The final step is to multiply 98 by the length of 20, this gives you 1960 meters cubed.
1) Multiply 14 by 14.
[tex]14*14=196[/tex]
2) Divide 196 by 2.
[tex]196/2=98[/tex]
3) Multiply 98 by 20.
[tex]98*20=196meters^2[/tex]

Answer:
2/5
Step-by-step explanation:
There are only 2 even number in the set out of 5 numbers.
The probability of selection even number at random is 2/5.
What is probability?
Probability is possibility that deals with "occurrence of random event at a time".
According to the question,
From the numbers 1,2,3,4,5
Number of sample space = 5
Number of even numbers = 2
Probability of an event = [tex]\frac{sum of favorable events}{Total number of events}[/tex]
In order to find probability of selection even number at random:
=2/5.
Hence, the probability of selection even number at random is 2/5.
