The measure of the exterior angle of the triangle is
O

Measure of exterior angle = 68°

Step-by-step explanation:

By exterior angle property of a triangle.

(7x - 16)°= (x + 8)° + (4x)°

(7x - 16)°= (x + 8 + 4x)°

(7x - 16)° = (5x + 8)°

7x - 16 = 5x + 8

7x - 5x = 8 + 16

2x = 24

x = 24/2

x = 12

Measure of exterior angle

= (7x - 16)°

=(7*12 - 16)°

= (84 - 16)°

Measure of exterior angle = 68°

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
