Question

What’s the correct answer for this?

Answer 1

The value of A is 60.1°

Explanation:

You have to use Trigonometric formula, sinθ = opposite/hypotenuse. Then substitute the following value into the formula,

`\sin(θ) = (oppo.)/(hypo.)`

Let θ = a,

Let oppo. = 13 units,

Let hypo. = 15 units

`\sin(a) = (13)/(15)`

`a= { \sin( (13)/(15) ) }^( - 1)`

`a =60.1 ° \: (1d.p)`
