Question

If cos A
12
13
then find sin A and tan A​

Answer 1

Answer:

Sin A = 5/13

tan A = 5/12

Step-by-step explanation:

cos A = 12/13 = B/H

By Pythagoras theorem:

H² = P² + B²

13² = P² + 12²

169 = P² + 144

P² = 169 - 144

P² = 25

P = √25

P = 5

Sin A = P/H

         = 5/13

Tan A = P/B

          = 5/12
