Question

Need explanation for how to find "E"(in the picture attached), and how to calculate "sin".​

Answer 1

Explanation:

E is just that Vertex/Angle.

`sin` is a measure of an angle.

You should learn SOHCAHTOA

`sin = opposite/hypotenuse\\cos(ine) = adjacent/hypotenuse\\tan(gent)=opposite/adjacent`

The opposite side is relative to the angle.

In this case, the opposite of E is 20

The hypotenuse is 29

so,

`sin(E)= (20)/(29)`
