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°)

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

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
