please help me solve this(i promise to give you a good review)

We will have the following:
First, we remember that the tangent for an angle in a right triangle is composed of the opposite side divided by the adjacent side, so:
Tan(B):
[tex]tan(B)=\frac{36}{27}=\frac{4}{3}\approx1.3333[/tex]Tan(A):
[tex]tan(A)=\frac{27}{36}=\frac{3}{4}=0.7500[/tex]
