Answer: -3
Step-by-step explanation:
7+2x/3=5
2x/3=-2
2x = -6
x = -3
Answer:
82*
Step-by-step explanation:
10x+8 = 12x-10
18 = 2x
X=9
Angle 1 = 98*
Angle 3 = 98*
180 - 98* = 82*
To simplify that equation you would first subtract 8 from both sides, getting 7x=28. You would then divide both sides by 7, getting x=4.
Third side must be greater than (12 -7) or 5 and less than (12 + 7) or 19
So, third side could be A C E or F
