Question

The angles of triangle are (x + 10°), (2x – 30°) and x°. Find the value of x

(a) 30 (b) 50 (c) 60 (d) 40​

Answer 1

Step-by-step explanation:

as you know the sum of all the three sides of triangle is 180 , so

x + 10 + 2x - 30 + x = 180

4x - 20 = 180

4x = 200

x = 50

1st angle = 50 + 10 = 60

2nd angle = 2×50 - 30 = 70

3rd angle = 50
