The sum of adjacent angles on a straight line would be 180°.
Since x is on a straight line,what we need to do is to deduct the remaining two angles,here's what the equation would be like:
180°-90°-30°
=60°
Thus,x=60°
hope it helps!
If you’re finding the measure of its complement, the sum of both angles will always be 90*
x+38 = 90
-38 | -38
x = 52
the measure of its complement is 52*
Rational because you get a whole number
