Question

URGENT I NEED HELPPP

Answer 1

Explanation:

The only valid expression from the given list is the one that uses the arctangent (
`tan^(-1)(0.75)` ) function.

Recall that the tangent of an acute angle in a right angle triangle is defined as:

`tan(B)=(opposite)/(adjacent)`

therefore in our case we have:

`tan(B)=(opposite)/(adjacent) \\tan(B) = (12)/(16) \\tan(B)=0.75\\B=arctan(0.75)`
