Answer:
u= -4
Step-by-step explanation:
-36=9u
u=-36/9
u=-12/3
u=-4
Neither are correct.
62 + 39 + angle c = 180
101 + angle c = 180
angle c = 79
angle x + 39 + 79 = 180
angle x + 118 = 180
angle x = 62
angle x = angle a,
angle Y = angle b,
angle c = angle z
first one i think Good luck
2m+-m=7
3m-8=7
Then add 8 to both sides of the equation.
simplify.
Divide both sides of the equation with the same term.
m=5
