Question

In geometry
If M angleA=48degree,then M angleB=? and M angleC=?
angleA and B are complementary and angle B and C are supplementary.

Answer 1

Angle A=48
since A&B are comp. that means they = 90 So 90-48= 42.
B&C supp. that means they =180. So 180-90=90.a=48,b=42,c=90.

Answer 2

If angles A and B are complementary they add up to 90 degrees. So figure out what plus 48 degrees equals 90 degrees.

If angles B and C are supplementary they add up to 180 degrees. So once you find the measure of angle B figure out what you have to add to that angle to get to 180 degrees.

Hope this helps. Good Luck.

Answer 3

Angle B = 42
Angle C = 138

Complementary Angles add up to 90 degrees
Supplementary Angles add up to 180 degrees
