Question

Calculate the magnitude of y. trapezium

K = 123°
L = 71°
M = 39°
N = y​

Answer 1

Answer: 127

Step-by-step explanation:

A trapezium has four sides, so it is a quadrilateral.

Any quadrilateral has all four interior angles add to 360 degrees.

K+L+M+N = 360

123+71+39+y = 360

233+y = 360

y = 360-233

y = 127
