Question

For the given triangle find the exact value for sin(A). Assume angle C is a right angle.

Answer 1

53.13 degrees

Explanation:

In order to use sin we have to use the opposite side over the hypotenuse.

`(4)/(5)` in this case

sin(A) =
`(4)/(5)`

`A = sin^(-1) (4)/(5)`

Plugging this into the calculator you get about 53.13 degrees
