Since triangles always have a total amount of 180 degrees, adding the amounts we already know and subtracting that amount from 180, we get the value x. So the answer would be 80 degrees.

Answer: In a triangle, the sum of the 3 angles is always equal to 180°

Then if the angle A is equal to 30°, the angle B is equal to 70°, what is the angle C?

if x is the angle C, and using the first statement, we got:

30° + 70° + x = 180°

100° + x = 180°

x = 180° - 100° = 80°

So the angle of C is equal to 80°.
