Answer:
x = 25/2
y = 5
Step-by-step explanation:
The angles are corresponding angles and corresponding angles are equal when the lines are parallel
4x+8y = 18y
We also know that 18y +90 = 180 since they form a straight line
18y +90 = 180
Subtract 90 from each side
18y+90-90=180-90
18y = 90
y =5
Now we can solve for x
4x+8y = 18y
4x+8y-8y = 18y-8y
4x = 10y
Since y = 5
4x = 10(5)
4x = 50
4x/4 = 50/4
x = 25/2
x = 50/4
Answer:
d = 18.02 m
Step-by-step explanation:
Given that,
A rectangular lawn has a diagonal path running across it. The lawn is 10m wide and 15m long.
We need to find the length of the path.
The diagonal of a rectangle can be calculated as follows :

So, the length of the path is 18.02 m.
Answer:
