Answer:
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 = [tex]\frac{opposite side}{hypotenuse}[/tex]
cos Ф = [tex]\frac{adjacent side}{hypotenuse}[/tex]
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
