The area of triangle abc is 95 square feet. what is the value of b, to the nearest foot?
a) 7 ft
b) 8 ft
c) 13 ft
d) 16 ft

D

Step-by-step explanation:

The area (A) of a triangle is calculated using

A = 0.5 absinC

Here a = 13 and ∠C = 65°, hence

A = 0.5 × 13 × b × sin65° = 95, that is

6.5b × sin65° = 95 ( divide both sides by 6.5sin65° )

b = ≈ 16 ft ( to the nearest foot )
