Question

In triangle ABC, angle A is 12 degrees and angle B is 100 degrees. How many degrees is angle C?*

Answer 1

In triangle ABC, angle A is 12 degrees and angle B is 100 degrees. How many degrees is angle C?*​

Remember that

In any triangle the sum of its three interior angles must be equal to 180 degrees

so

A+B+C=180

substitute the given values

12+100+c=180

solve for c

112+c=180

c=180-112

c=68 degrees
