I need to now the measurements on of A and B

A = 90° and B = 145°

Step-by-step explanation:

We already know that A is a right angle because it looks just like one. A trapezoid has a total of 360 degrees. We can create an equation to solve for the 4th angle.

90 + 90 + 145 + x = 360

325 + x = 360

x = 35

Now, we can find B. Angle B and 35 make a supplementary angle. This means that both angles when added will equal 180 degrees. We can create an equation and solve.

35 + B = 180

B = 145

Best of Luck!

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
