Given: if two angles are complementary, then both angles measure less than 90°. angles that measure less than 90° are acute. ∠1 and ∠2 are complementary. what conclusion can be drawn?
a only ∠1 is acute.
b only ∠2 is acute.
c both angles are acute. d neither angle is acute.

C. Both angles are acute.

Step-by-step explanation:

Acute means less than or equal to. So 90° is an acute angle. Complementary angles means boths angles sum up to form 90°. Angle 1 & 2 must be lesser than 90° in order to form a complementary angles.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
