Question

HELP with this equation

Answer 1

1. -4m+51+(-4m+43)=158
2. -8m+94=158
3. -8m=64
4. m=-8

Now you plug in m for the angle equation.
-4(-8)+51
32+51
83 degrees is the answer

Answer 2

83°

Explanation:

-4m+51-4m+42= 158°

-8m+94= 158

-8m= 64

m= -8

JMK= -4m+51

= -4(-8)+51

= 32=51

= 83°
