Question

In a triangle, the measure of angle A is 3times the measure of angle B, and the measure of angle C is 5 degrees more than the measure of angle B. What is the measure of angle A?

Answer 1

find x by solving the equation : <A + <B + <C = 180
then plug into A...

Answer 2

let angle B be x. The Angle A will be 3x and angle C will be x+5. Since all angle sums 180, then x + 3x + (x+5)=180, 5x+5=180. Therefore, x=35 Thus Angle A which was 3x will be 105
