Question

Find the tan A and sin B exactly.

Choices -

A - tan A = 3/4, sin B =5/3

B - tan A = 4/3, sin B = 3/5

C - tan A = 3/4, sin B = 3/5

D - tan A = 4/3, sin B = 5/3

Answer 1

• B - tan A = 4/3, sin B = 3/5

Explanation:

First, lets find the length of the third side

• b = √15² - 12² = √225 - 144 = √81 = 9

Now, lets get Tan A and Sin B

• Tan A = 12/9 = 4/3
• Sin B = 9/15= 3/5

Correct option is B
