Answer:  The two angles add up to 180 so they are supplementary angles.  

The sum of their measures is 180 degrees.

Step-by-step explanation:

Plug in given value for x.  

x=20

(3x+50)=

(60+50)=110

110

(4x-10)=

80-10=70

70

There are several true things about these angles you can find from this information but I think you are looking for the answer at top.
