Question

How do you calculate angles on a straight line??

Answer 1

Answer:

x + y =180 (degrees)

Answer 2

Explanation:

Straight line is an angle whose vertex point(O) has a value of 180. The arms (OA & OB) of the straight line angle lies opposite to each other from the vertex point

Sum of all the angles in a straight line = 180

From this you can find the value of unknown angle, if other angles are given.

∠AOC + ∠BOC = 180
