I thought it was B, but it says it's wrong. Its definitely not D, so A or C?

Answer 1

9514 1404 393

Answer:

A) B = 37.2°, b = 309.1, c = 382.3

Explanation:

You know the third angle must be ...

B = 180° -131.6° -11.2°

B = 37.2° . . . . . . eliminates choice D

You know the two missing sides are both longer than 99.3, eliminating choice C.

Since angle C is the largest angle, side c is the longest side, eliminating choice B.

By the process of elimination, we know the correct choice is A.

__

The Law of Sines will tell you the length of side C is related to the other triangle values by ...

c/sin(C) = a/sin(A)

c = (99.3 ft)×sin(131.6°)/sin(11.2°)

c ≈ 382.3 ft . . . . matches choice A
