Question

hai mates please me​

Answer 1

Answer:

let the angle be x then,

according to the question,

other angle = 180-x also,

x = 2/7(180-x)

now,

x + (180-x) = 180° ( supplementary angles)

putting value of x

2/7(180-x) + (180-x) = 180°

or, (360/7-2x/7) + (180-x) = 180°

or, 360/7-2x/7 + 180 - x = 180°

or, -2x/7-x = 180°-180-360/7

or, -2x/7-7x/7 = -360/7

or, -9x/7 = -360/7

or, -9x = -360/7×7

or, -9x = -360

or, -x = -360/9

or, -x = -40

or, x = 40

hence, the angle is equal to 40°.
