Which equation can be used to solve for b?
b
5 cm
10 cm
30°

The Question is Incomplete The complete question with figure is below.

Therefore the equation to solve for b is

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠C = 90°

BC = 5 cm

AB = 10 cm

∠A = 30°

To Find:

b = ?

Solution:

In Right Angle Triangle ABC Tangent identity we have

Substituting the values we get

Therefore the equation to solve for b is

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

no
