Given m
|| n, find the value of x and y.
(4x-6)
(8x+18)
(y+3)

Step-by-step explanation:

(4x-6)+(8x+18) = 180°

12x+12 = 180

12x=168

x=14° ..(1)

8x+18=y+3.. (putting the value of x from equation1)

72+18-3=y

y= 87°

hope this helps you.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

i belive those are the ones that are under 90 degreese.
