Find the value of x that makes m ∥ n.

x=90

Step-by-step explanation:

If m//n , then the 2 angles should be congruent because of the exterior angle theorem.

Since they should be congruent, we can set them equal to each other

180-x=x

Add x to both sides

180-x+x=x+x

180=2x

Divide both sides by 2

180/2=2x/2

90=x

x° = 90

Step-by-step explanation:

Since m ║ n, we can assume that the two angles given here are alternate interior angles that are equal.

Therefore:

Solve for x by adding x to both sides. You will get:

Divide each side by 2 to isolate the x. You will get:

it is 570

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
