<IMK=<GMH because they are vertical angles. Therefore:
84=4x
<em>*Divide both sides by 4*</em>
21=x
<IMK+<KMH=180 because they are supplementary angles. Therefore:
84+<KMH=180
<em>*Subtract 84 from both sides*</em>
<KMH=96
Hope this helps!!
I hope this helps you
7x-4x = -9-12
3x=-21
x= -7
The answer I believe is -36
