Answer:
Assuming the wall is flat, X = 50.5
Step-by-step explanation:
180 degrees - 79 degrees = 101
101 / 2 = 50.5
Hope this helps :)
First solve for x in the first equation
x + 7y = 0
x = -7y
since x = -7y we can substitute -7y into the other equation wherever there is an x
2x - 8y = 22
2(-7y) - 8y = 22
-14y - 8y = 22
-22y = 22
y = -1
Now let's substitute -1 back into either of the original equations so we can solve for x
x + 7y = 0
x + 7(-1) = 0
x - 7 = 0
x = 7
So your solution set is
(7, -1)
Answer:
D-2
Step-by-step explanation:
You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2
