The measure of angles of a triangle are x°, (x-20)' (X-40°) Find the measure of each angle.​

Answer 1

Answer:

80°,60°,40°

Step-by-step explanation:

X°+X-20°+X-40°=180

3X-60=180

3X=180+60

3X=240

X= 240

3

X=80

X-20=60

X-40=40

Answer 2

80°,60°,40°

Step-by-step explanation:

X°+X-20°+X-40°=180

3X-60=180

3X=180+60

3X=240

X= 240

3

X=80

X-20=60
