Question

The measures of anglesof a triangle are x degree, ( x-20 ), ( x-40 ). Find the measure of each angle. n

Answer 1

Answer:

A=80,B=60,C=40

Step-by-step explanation:

We know that angles of a triangle add up to 180.

Using that we get,

x+ x-20 +x-40=180

x+x+x-20-40=180

3x-60=180

3x=180+60

3x=240

x=240/3=80

Therefore,

Angle A=80

Angle B=80-20=60

Angle C=80-40=40
