Question

Angles of a triangle are x ,(x+ 10)
degree and 70 degree find the two angles of a triangle

Answer 1

Answer:

1st angle = 50°

2nd angle = 60°

Step-by-step explanation:

let, 1st angle be x

and 2nd angle be (x+10)

So,

x+(x+10)+70°=180° (sum of all interior angle)

x+x+10+70°=180°

2x+80°=180°

2x=180°-80°

2x=100°

x=100°/2

x=50°

Now, 1st angle = 50°

2nd angle = 60°
