Answer:
y = 47
Step-by-step explanation:
All of the angles in a triangle must add up to 180. The angle marked 3y can help us find the missing angle of the triangle: 180-3y
Then you can make an equation to help solve for y:
50 + (2y-3) + (180-3y) = 180
Combine like terms:
227-y=180
y = 47
Answer:
x=-14
Step-by-step explanation:
-2(x-8)+4x= -12
-2x+16+4x=-12
2x=-28
x=-14
Answer:
Step-by-step explanation:
If width =x
Length =x + 5
Perimeter =x+x+5+x+x+5
26=4x+10
16=4x
X=4
Therefore width =4
Length =9
