Answer 1

This a question my students have problems with

Answer 2

Explanation:

Soh Cah Toa

S stand for sine, C stand for Cosine and the T stand for Tangent

'o' is the opposite, 'a' stand for adjacent (next to) and h stand for hypotenuse (the longest length of the triangle)

`sin(\theta)=(opposite)/(hypotenuse)`

`cos(\theta)=(adjacent)/(hypotenuse)`

`tan(\theta)=(opposite)/(adjacent)`

We care about angle A and we want sine. So we will use the first equation.

The opposite from A is 3 and the hypotenuse is 5.

`sin(A)=(3)/(5)`
