Question

The angles of a triangle length are x degree, (x+10degree), and (x+20degree). find the value of x and the angles​

Answer 1

Step-by-step explanation:

we know that the sum of all angles in a triangle is 180 degree , then

x+(x+10)+(x+20) =180

3x +30 =180

3x = 180-30

3x = 150

x=150/3

x= 50

the value of angles:-

x= 50°

x+10 =(50+10)=60

(x+20) =(50+20)=70 , answer....
