Answer:
<h2>66 and 66</h2>
Step-by-step explanation:
opposite angles are equal
12x - 18 = 8x + 10
combine similar terms:
12x - 8x = 10 + 18
4x = 28
x = 28/4
x = 7
plugin the value of x=7 back into the equation to solve the angle
= 12x - 18
= 12(7) - 18
= 66
= 8x + 10
= 8(7) + 10
= 66
Answer: you got this

M= slope B = y intercept
So the 4 would be the slope and the -5 would be the y intercept
Answer:
(C) 10m + 7n - 14
Step-by-step explanation:
[Q-R]+[S-T] =[(7m+3n)-(11-2m)]+[(n+5)-(-m-3n+8)]=
=[7m+3n-11+2m] + [n+5+m+3n-8]=[9m+3n-11] + [4n+m - 3]=
=9m+3n-11+4n+m-3=10m + 7n - 14
The problem = n - 8 = -4
Switch it around and it becomes:
-4 + 8 = n
-4 + 8 = 4
n = 4
