Answer:
the smaller angle=39°
the larger angle=51°
Step-by-step explanation:
the two angles we are looking for will add up to 90° since they are complementary angles
the smaller angle is rep by 2x
the larger angle is rep by 2x+12
then u equate to 90° since they r complementary angles
2x+2x+12=90°
4x=78x=19.5
x=19.5
2(19.5)=39°
2(19.5)+12=51°
