Question

What is the value of A in this equation? sin(53.2°) = cos(A)
(I need this answer ASAP please)

Answer 1

`A= 35.8`

Explanation:

Given

`sin(53.2) = cos(A)`

Required

Find A

In trigonometry

`sin(\alpha) = cos(\theta)`

Then

`\alpha + \theta = 90`

So, this gives:

`54.2 + A= 90`

Make A the subject

`A= 90-54.2`

`A= 35.8`
