Question

Please help me in this assignment.

Answer 1

Tan(A) = opposite / adjacent
if we call opposite "a" and adjacent "b"
tan(A) = a/b
then...
tan(B) = b/a
because it's on the other angle so "b" is now opposite angle B and "a" is adjacent.

So really you just need to take the reciprocal of the given values.

6. tan(A) = 1.25
reciprocal is flipping the value and using it to divide by 1.

you can keep as decimal , 1/1.25 = 0.8
or change to fraction
1.25 = 5/4

tan(B) = 4/5 or 0.8

7. tan(B) = 0.5
1/0.5 = 2
tan(A) = 2

8. tan(B) = 1
tan(A) = 1
