In triangle ABC, angle A is 23 degrees and angle B is 76 degrees. What is the percentage of the sum of the angles of the triangle is the angle C?
The angles in a triangle add up to 180 °.
If angle A = 23 °, angle B = 76 °, then to find angle C, you need to subtract the sum of two known angles from 180 °.
23 + 76 = 99 ° sum of 2 angles.
180 – 99 = 81 ° is equal to the angle C.
180 ° is 100%, then the angle C occupies:
81: 180 * 100 = 45% of the sum of the angles.
