Answer:
see below
Explanation:
a) set the two equations equal to each other and isolate the variable
3x+8 = 7x-24
3x+32=7x
32=4x
x=8
b) Plug in the value of x we got into the equation
7(8)-24 = 56
56-24=32
c) Angle k and h are both 72 (add 20 and 502 together) so h+k=144
J and m are going to have the same measurement so we can set up and equation, we also know all angles must add up to 360
144+2x=360
2x=216
x=108
HMK=108
