Question

If 3tana is equal to 4 then find soma and cos a

Answer 1

Answer:

Your answer is here.

Step-by-step explanation:

Given, 3tanA = 4

=> 3tanA = 4

=> tanA = 4/3

We know that

tan = p/b

So, p = 4 and b = 3

By Pythagoras theorem,

=> H² = P² + B²

=> H² = 4² + 3²

=> H² = 16 + 9

=> H² = 25

=> H = √25

=> H = 5

CosA = B/H

=> CosA = 3/5 Answer.

I hope it will you.
