We know that the angle of a straight line is 180°.
So we know that (5x-5) + (2x+10) = 180
We will then solve for x
5x - 5 + 2x + 10 = 180
7x + 5 = 180
7x = 175
x = 25 (just an explanation of how we get 25)
To get angle 1, we will then plug in x=25 into the first equation to get
5(25)-5 = 125-5 = 120°
Answer:
a and c are alternate interior angles
It would be 7/48 or the decimal would be 0.15
Area of a square= length^2
479=length^2
√479= length
so length= 21.89ft rounded to 22ft
