What is the length of PR?

Given in the image we see that two angles of ∆XYZ and ∆PQR are equal respectively ie 40° and 110°. Thus their third angle would also be equal.

Hence, ∆XYZ and ∆PQR are similar by AAA condition.

Now, since corresponding sides are in proportion, we can say that~

Therefore, length of PR is 9 units.

Hope this helps :)

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
