value of adjacent angle 2x+30 and 2x+10 of a straight line

options:-

a)80°

b)70°

c)60°

d)20°​​

Answer 1

Answer:

The sum of two adjacent angles = 180°

so

$2x + 30 + 2x + 10 = 180 \\ 4x + 40 = 180 \\ 4x = 180 - 40 \\ 4x = 140 \\ x = \frac{140}{4} \\ x = 35$

$2x + 30 = (2×35) + 30 \\ 70 + 30 \\ 100$

$2x + 10 = (2×35) + 10 \\ 70 + 10 \\ 80$
