Two sides of a right triangle ABC C is the right angle are g

Two sides of a right triangle ABC (C is the right angle) are given. Find the indicated trigonometric function of the given angle. Give exact answers with rational denominators. Find tan A when a = 9 and b = 8

Solution

We have given a=9 and b=8

Fron Two sides of a right triangle ABC

We get a is oppsite side ,b is adjacent side and c will be the hypotenuse

tanA=opposite side/ adjacent side =a/b =9/8

tanA=9/8
