Question

1. The measure of angles of a triangle are x°, (x-40)º, (-50)°. Find
measure of each angle.​

Answer 1

Let the angles be x,x-40,x-50

so,

x+(x-40)+(x-50)=180 ( angle sum property of a triangle)

3x-90=180

3x=180+90

3x=270

x=270/3

x= 90

Now,we need to substitute the value of x

so the angles will be 90°,50°,40°
