Find the measures of the interior angles.

angle A= 30

angle B= 90

angle C= 60

Step-by-step explanation:

Remember that the measures of the degrees in a triangle always sum up to 180 degrees. So the equation would be: 30+90+x= 180.

Step 1- Add to simplify.

(30+90)+x= 180

120+x= 180

Step 2- Subtract 120 to both sides.

120+x= 180

-120      -120

x= 60

Hope this helps! :)

Angle A = 30°

Angle B = x = 60°

Angle C = 90°

Step-by-step explanation:

30° + 90° + x° = 180°

120° + x = 180°

x = 180° - 120°

x = 60°.
