Question

in triangle abc if angle A minus B is equal to 40 degree and Angle B minus C degree is equal to 10°, find the measure of angle A B and C ​

Answer 1

Answer:

Step-by-step explanation:

let angle A=x

angle B=x-40°

angle C=x-50°

in triangle sum of all angles is 180°

x+x-50°+x-40°=180°

3x-90°=180°

3x=270°

x=90°

angle A=90°

B=50°

C=40°
