Answer:
Angle A: 60
Angle B: 30
Angle C: 90
Step-by-step explanation:
To figure out the angles, you need to set up an equation:
180 = x + x + 30 + x + 60
Add like terms:
180 = 3x+ 90
Solve for x
90 = 3x
divide by 3 to get x
30 = x
So, x is 30, and angle a is angle b plus 30, which is 60. angle c is x plus 60, which is 90.
