Question

To the nearest degree, find the measure of angle A

Answer 1

the answer is 25.841 ..:• to nearest degree..it is 26

Answer 2

Option A, 26°

Explanation:

In the given right angle triangle we have to find the nearest measure of angle A.

By cosine law,

`cosA=(Base)/(Hypotenuse)`

`=(18)/(20)`

= ( 0.90)

A =
`cos^(-1)(0.90)`

= 25.84°

≈ 26°

Option A is the answer.
