Question

Which equation can be used to solve for b?
o b= 0)tan(30°)
Ob
8
tan(30)
b = (8)sin(309)
b=-
sin(30°)

Answer 1

Answer:8tan(30)

Step-by-step explanation:

It is right angle triangle. The given data includes angle 30 and the side "b" infront i.e. perpendicular and the base 8ft.

So tan(30)=b/8

Answer 2

The equation that can be used to solve for b is as follows:

b = 8 tan 30°

Properties of a right angle triangle:

• One of its angle is 90 degrees.

• The sides and angles can be found using trigonometric ratios like sine, tangent and cosine.

The triangle above is a right angle triangle. The side b can be found as follows:

Using trigonometric ratio,

tan 30° = opposite / adjacent

opposite side = b

adjacent side = 8 ft

Therefore,

tan 30° = b / 8

cross multiply

b = 8 tan 30°
