Question

In the figure given below, calculate x and y.

Answer 1

x= 73. y=39. 180-107=73 and since it is a straight line the angle is 180. and 90-51= 39 because a right angle is 90 degrees and since the other side was a right angle that means that angle has to be a right angle too

Answer 2

x = 73°

y = 39°

Explanation:

x + 107 = 180 {Linear pair}

x = 180 - 107 {Subtract 107 from both sides}

x = 73°

y + 51 + 90 = 180 {straight line angles}

y + 141 = 180

y = 180 - 141

y = 39°
