Consider a triangle ABC like the one below. Suppose that a = 47, b = 59, and A = 37" (The figure is not drawn to scale.) Solve t

Yanka [14]

Answer:

B = 49.1°

C = 93.9°

c = 77.9

Step-by-step explanation:

Given:

a = 47, b = 59, and A = 37°

Required:

B, C, and c

Solution:

✔️To find B, apply the law of sines:

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

Plug in the values

$\frac{sin(37)}{47} = \frac{sin(B)}{59}$

Cross multiply

$47*sin(B) = sin(37)*59$

Divide both sides by 47

$\frac{47*sin(B)}{47} = \frac{sin(37)*59}{47}$

$sin(B) = 0.7555$

$B = sin^{-1}(0.7555)$

B = 49.0690779° ≈ 49.1° (nearest tenth)

✔️C = 180° - (A + B) (sum of triangle)

C = 180° - (37° + 49.1°)

C = 93.9°

✔️To find c, apply the law of sines:

$\frac{sin(B)}{b} = \frac{sin(C)}{c}$

Plug in the values

$\frac{sin(49.1)}{59} = \frac{sin(93.9)}{c}$

Cross multiply

$c*sin(49.1) = sin(93.9)*59$

Divide both sides by sin(49.1)

$c = \frac{sin(93.9)*59}{sin(49.1)}$

c = 77.8766982

c ≈ 77.9 (nearest tenth)

The height of the house is 26 feet. What is the height x of each story?

Iteru [2.4K]

X = stories of houses.

x ÷ 26 = the amount of the hiegth of the story.

It would all depend on the amount of stories this house or building would contain.

If the volume of a box is 1/8 cm^2 what are the lengths of its sides

mrs_skeptik [129]

Answer:

(1/2) cm = x

Step-by-step explanation:

This box has the shape of a cube. The formula for the volume of a cube is V = x^3, where x is the length of any one side of the cube.

Here the volume is (1/8) cm^3. We set this equal to x^3 and solve for x:

Taking the cube root of both sides, we get:

(1/2) cm = x
