Answer:
Step-by-step explanation:
You are going to be using the Cos function.
<B = 50 degrees
BC = 2
AB is what you want
Cos(50) = adjacent / hypotenuse
Cos(50) = 2/hypotenuse Multiply both sides by the hypotenuse.
hypotenuse*Cos(50) = 2 Divide by cos(50)
hypotenuse = 2 / cos(50) Cos(50) on the left cancels. Divide.
hypotenuse = 2 / .6428
hypotenuse = 3.111 = 3.1
sin < C = c/a
cos < C = b/a
tan < C = c/b
Multi the first two number then divide the last and you’ll get the answer
54.50
10 * 5 + 9%
50 + 9% (4.50) = 54.50
