Question

What value of x will make angle aob is a straight line in which other angles are 2 X + 10 degree and 2 x minus 30 degree

Answer 1

Answer:

x=50

Step-by-step explanation:

(2x+10°) + 2x-30°=180°( angles on a straight line)

2x+2x=170°+30°

4x=200°

x=200/4

x=50

Answer 2

Answer:

50°

Step-by-step explanation:

(2x+10) +(2x -30) = 180 (as a straight line will make an angle of 180°)

4x = 180 + 20= 200

x = 200/4 = 50°
