Question

Find the measure of angle C of a triangle ABC if measure of angle a = 24 degrees and measure of angle b = 130 degrees

Answer 1

26 degrees.
For any regular convex polygon with n sides, the sum of all its interior angles will be (n-2)*180.
Using this we know that the sum of all the angles will be 180 degrees.
24+130+x=180
154+x=180
x=26
