In the parallel lines the value of x will be 155 or 171 and value of y will be 9 or 25.
<h3>What are parallel lines?</h3>
Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions
The angles y²and 8y-15 are alternate angles.
We know that the alternate angles are equal.
So
y²=8y-15
y²-8y+15=0
y²-5y-3y+15
y(y-5)-3(y-5)
(y-3)(y-5)=0
y=3 and y=5
So when y=3, 8(3)-15
24-15=9
So when y=5, 8(5)-15=25
Hence
The sum of angles should be 180
x+(8y-15)=180
x+25=180
x=180-25
x=155
and
x+(8y-15)=180
x+9=180
x=180-9
x=171
Hence value of x will be 155 or 171 and value of y will be 9 or 25.

Answer:
Step-by-step explanation:
The basic idea is to factor each expression and cancel common factors from numerator and denominator.
Answer:
15
Step-by-step explanation:
Answer:
1.25 hours
Step-by-step explanation:
If you're going 60 miles per hour, that's exactly how much miles you travel in an hour if that is your constant speed you are going the entire time, so it is at least 1 hour and we know it's not 4500 hours and it cant be .8 hours or 135 hours, think of yourself going on a caride would it really take 135 hours ? No so its 1.25. Also multiply 60 by 1.25 and you get 75.
115 - 40 = 75
Because 115 is the total and your getting rid of the 40 other degrees in the 115
