Question

if x y and z are the angles on a line AB, find y. x = 45° , z = 86°​

Answer 1

Answer:

y = 49°

Step-by-step explanation:

Assuming the line AB is a straight line

We know that angles on a straight line are supplementary, their sum is 180°

x + y + z = 180

45 + y + 86 = 180

y+ 131 = 180

y = 49°
