What Is The Length Of AC In The Given Triangle class=

Sagot :

Answer: the answer is 126.6

Step-by-step explanation:

Answer:

  AC ≈ 126.6

Step-by-step explanation:

The law of sines can be used to find the side length of interest in this triangle. It tells you ...

  a/sin(A) = b/sin(B) = c/sin(C)

__

missing angle

In order to use the law of sines, we must have a side length and its opposite angle. Here, the angle opposite the given side is unmarked, so we need to compute it using the angle sum theorem.

  A +B +C = 180°

  A +85° +53° = 180°

  A = 42° . . . . . . . . . . . . . subtract (85°+53°)

unknown side

Then side AC can be found from ...

  AC/sin(B) = BC/sin(A)

  AC = BC·sin(B)/sin(A) = 85·sin(85°)/sin(42°)

  AC ≈ 126.547

The closest answer choice is 126.6.
