Question

If tan A = 3/4, then sin A cos A=__​

Answer 1

Answer:

12/25

Step-by-step explanation:

tanA = 3/4 ⇒

p/b = 3/4

⇒ p = 3 & b = 4

Therefore, h=√(3)² + (4)² = 5

Hence, sinA cosA = p/h×b/h = pb/h² = (3×4)/25² = 12²/25² = 12/25

Answer 2

Answer:

sin A cos A=12/25

Step-by-step explanation:

Tan A=3/4

opposite side is 3

adjacent side is 4

and hypotenuse is 5
