Answer 1

Answer:

X = 32

Step-by-step explanation:

angles in the straight line add up to 180 therefore

(2x + 60) + (3x - 40) = 180

5x + 20 = 180

5x = 180 - 20

5x = 160

X = 32

Answer 2

Step-by-step explanation:

sum of both is 180

Equation :

(2x+60)+ (3x-40) = 180

2x+60+3x-40 = 180

2x+3x = 180-60+40

5x = 160

x = 160/5

x = 32

1st angle = 2×32+60 = 124

2nd angle = 3×32 - 40 = 56

Verification : 124 + 56 = 180

Hence proved
