Question

Find the Sine of angle A
8/17
8/15
15/8
15/17

Answer 1

Given:

In triangle ABC, AB = 30, BC = 16, AC = 34 and measure of angle B is 90 degrees.

To find:

The value of Sine of angle A.

Solution:

In a right angle triangle,

`\sin\theta=(Perpendicular)/(Hypotenuse)`

In the given triangle ABC,

`\sin A=(BC)/(AC)`

`\sin A=(16)/(34)`

`\sin A=(8)/(27)`

Therefore, the correct option is A.
