This one is a bit confusing without a diagram anyway. We'll assume the typical labeling where A and B are consecutive angles, so the transverse line AB through the parallels makes A and B supplementary:
A + B = 180 degrees
12x + 46 + 7x + 1 = 180
19x = 180 - 47 = 133
x = 133/19 - 7
Answer:
2
Step-by-step explanation:
A polygon must have at least 3 sides, but a curved angle isn't a side. This would result in you getting an oval. In short, it would not be a polygon. Hope this helps!
Answer:
<u>3808ft²</u>
Step-by-step explanation:
Formula: A=L×W
<u>A=</u> area
<u>L=</u> length
<u>W=</u> width
A= 112 × 34= <u>3808ft²</u>
Answer:
Given system of equations:
To solve by substitution, equate the equations and solve for x:
Therefore, the x-values of the solution are 
and 
.
To find the y-values of the solution, substitute the found values of x into the functions:
Therefore, the solutions to the given system of equations are:
and
