The answer to your question is a = 9.456; b = 7.388

Step-by-step explanation:

Process

1.- To find "a" and "b" we must use the trigonometric functions sine and cosine.

sin Ф = $\frac{opposite side}{hypotenuse}$

cos Ф = $\frac{adjacent side}{hypotenuse}$

2.- Determine "a"

a = adjacent side = hypotenuse x cos Ф

a = 12 x 0.788

a = 9.456

3.- Determine "b"

b = hypotenuse x sin Ф

b= 12 x 0.616

b = 7.388
