Question

What is the length of AC

Answer 1

The answer is B, ane i do not know how to explain this

Answer 2

Option A

Explanation:

In the given right angle triangle ABC,

BC = 15 m and m∠A = 55°

We have to calculate the measure of side AC.

Since tanA =
`(Height)/(Base)`

tan55 =
`(15)/(AC)`

1.428 =
`(15)/(AC)`

1.428(AC) = 15

AC =
`(15)/(1.428)`

AC = 10.5 m

Therefore, Option A. AC = 10.5 m is the answer
