Question

Triangle ABC is a right triangle. ∠A measures 48°. What is the measure of ∠C?

Answer 1

42°

Explanation:

angles in a triangle add up to 180°

angle B 90°. 90 ° because this is a right-angled triangle. how do we know that B is the 90° degree? because we are told ABC. the letter in the middle is the angle.

so for angle A (48°), we could be told that angle CAB = 48°. A is in the middle of CAB.

as for our missing angle C, this can be found by subtracting the sum of the other two angles from 180.

angle C = (180 - 90 - 48)°

= 42°
