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:

a .4y4

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
