Question

The measure of angles of a triangles ar x°,(x-20°) and (x-40)° .Find the measure of each angle
​

Answer 1

Answer:

x=80°

(x-20)=80-20=60°

(x-40)=80-40=40°

Step-by-step explanation:

x + (x-20) + (x-40) =180° ...angle sum property of a triangle

x+x-20+x-40=180

3x-60=180

3x=180+60

x= 240/3

x=80°

substituting x=80,

(x-20)=80-20=60°

(x-40)=80-40=40°
