Question

the angles of a triangle are X + 40 degree 2 x - 10 degree and X + 50 degree find the value of x​

Answer 1

Step-by-step explanation:

Sum of interior angles of a triangle equals to 180

that is,

(x + 40) + (2x - 10) + (x + 50) = 180

4x + 80 = 180

4x = 100

x = 25

1st angle: x + 40 = 25 + 40 = 65°

2nd angle: 2x - 10 = 2(25) - 10 = 50 - 10 = 40°

3rd angle: x + 50 = 25 + 50 = 75°

Checking correctness:

1st angle + 2nd angle + 3rd angle = 180?

65 + 40 + 75 = 180

180 = 180

CORRECT
