Answer:
'tan A + tan B ' This term is used in a mathematics chapter called trignomety . In this triangle , A is the angle between b and c. And tan A is given as perpendicular devided by base . So, tan A = a/b , sin A = a/c , cos A = b/c .
Step-by-step explanation:
According to the figure,
In △ABC, ∠C=90
∘
.
By Pythagoras theorem,
We can say that,
c
2
=a
2
+b
2
Also,
tanA=
b
a
and tanB=
a
b
We have,
tanA+tanB=
b
a
+
a
b
=
ab
a

+b

=
