Question

What is the side of a? how would i find a?

Answer 1

Given an angle on a right triangle, the ratio between the opposite leg and the hypotenuse is equal to the sine of the angle.

`\sin\theta=(A)/(B)`

Using this property in our problem, we have the following relation for the missing side:

`\sin41^o=(a)/(16)\implies a=16\cos41^o=10.49694...\approx10`

The length of the missing side is 10m.
