Question

One angle of a line appeared is 80 degree then the The other find the two angles

Answer 1

one angle = 80

other two angle be x

according to the question

80 + x + x = 180

80 + 2x = 180

2x = 180 -80

2x = 100

x = 100/2

x = 50

so other two angles be 50

Answer 2

Answer:

one of the angle is 80

other two angle = x, x

the sum of three angles is 180

$x + x + 8 0 = 180 \\ 2x + 80 = 180 \\ 2x = 180 - 80 \\ 2x = 100 \\ x = \frac{100}{2} \\x = 50$

the two angles are 50, 50
