Answer:
53
Step-by-step explanation:
Angle DCB is equal to the sum of the 2 interior angles (Angle CBA & angle BAC)
So:
(3y + 8) + 4y = 113
(3y + [8-8]) + 4y = 113-8
3y + 4y = 105
7y = 105
7y/7 = 105/7
Y=15
Plug it into the equation:
3(15) + 8
45 + 8

Answer:
6.53
Step-by-step explanation:
cos(theta)= adjacent/hypotenuse
cos(40)= 5/h
H= 5/cos(40)
=6.527
