Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of t

alex41 [277]

Answer:

$\angle MKJ = 34$

Step-by-step explanation:

Given

$\angle LKJ = 124$

Required

Find $\angle MKJ$

From the attachment:

The measure of $\angle MKJ$ is calculated using the following expression:

$\angle MKJ + \angle LKM = \angle LKJ$

Where

$\angle LKM = 90$ -- right-angled.

The expression becomes

$\angle MKJ + 90 = 124$

$\angle MKJ = 124 - 90$

$\angle MKJ = 34$
