Tell Whether The Angles Are Complementary Or Supplementary Then Find The Value Of X This Just Confused Me A Bit X 20 They Are Complimentary So Ik The Other Side class=

Sagot :

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55


Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.
