its 110 degrees

Step-by-step explanation:

It is a linear pair. Therefore, 180-70 give you 110 degrees

measurement of angle Q=60 degrees

Step-by-step explanation:

Because the two lines are parallel, you can assume that the intersecting lines have vertical angles. So, the 70 degree angle is equal to angle R, and the 50 degree angle is equal to the angle to the left of angle Q. 50+70=120, and 180-120=60 because angle Q, R, and the angle to the left of angle Q, added together is equal to a straight angle, or 180 degrees.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
