Question

Find the area of the triangle. Round your answer to the nearest tenth.

a.
1,352 ft2
b.
1,260.8 ft2
c.
922.1 ft2
d.
1,844.1 ft2

Answer 1

c

Explanation:

Given a triangle with 2 sides and the included angle the area is found using

A =
`(1)/(2)` bc sinA

here b = c = 52 and A = 43°, hence

A =
`(1)/(2)` × 52 × 52 × sin43° ≈ 922.1 ft² → c
