Answer:
m<GLK = 58°
Explanation:
Given:
m<GLH = 2x + 6
m<HLJ = x
Required:
m<GLK
Solution:
First, find the value of x
m<GLH + m<HLJ = 180° => Linear Pair Theorem
Substitute
2x + 6 + x = 180
Add like terms
3x + 6 = 180
3x + 6 - 6 = 180 - 6
3x = 174
3x/3 = 174/3
x = 58
m<HLJ = x = 58°
Thus, m<HLJ and m<GLK are Vertical angles.
Therefore:
m<GLK = m<HLJ (Vertical angles theorem)
m<GLK = 58° (Substitution)
