Question

In the diagram below of AGJK, H is a point onGJ, HJ = JK, m2 = 28, and mZGJK = 76.What is mZGKH?2870H

Answer 1

Problem

Solution

For the triangle GKJ we can find the angle K on this way:

28 +70 + Now we know that HJ= JK so then the triangle HJK is an isosceles triangle so then < JHK = < HKJ and we can do this:

70+ 2x = 180

2x= 110

x= 55

And then we can find the angle < GKH with the following equation:

28+70 + (55+y) = 180

y= 180-55 -28-70= 27
