Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

please mark me as the brainliest

Step-by-step explanation:

sin A = 3 / 4 = opposite / hypotenuse

(hypotenuse)² = (opposite side)² + (adjacent side)²

(4)² = (3)² + (X)²

x² = 16 - 9 = 7

X (adjacent side) = √7

cos A = adjacent / hypotenuse = √7 / 4

tan A = opposite / adjacent = 3 / √7 = (3√7) / 7
