Question

The three angles of a triangle are x x + 20 degree and x + 40 degree find the value of x

Answer 1

Answer:

Xx can be x²

Step-by-step explanation:

(X²+20degree) +(x+40degree)=180degree (interior angle sum property)

Answer 2

By Using angle sum property

x+x+20+x+40=180

3x+60=180

3x=120

x=40

x+20=60

x+40 80

then 40,60,80 are the required angles
