Question

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

Answer 1

Answer:

Step-by-step 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,

$sin(E)= \frac{20}{29}$
