Answer:

x = 35°

Step-by-step explanation:

These are corresponding angles. When a transversal crosses 2 parallel lines, 4 angles are created at each intersection, and each pair of corresponding angles between those are congruent.

These angles are congruent, so you can set them equal to each other:

2x+20=3x-15

Then, just solve for x:

20=x-15\\35=x\\x=35

You can check that by plugging it back into both:

2x+20=3x-15\\2(35)+20=3(35)-15\\70+20=105-15\\90=90

Answer:

x = 35

Step-by-step explanation:

The angles shown are corresponding angles

Corresponding angles are congruent ( equal to each other )

This means that 2x + 20 should equal 3x - 15

Note that we've just created an equation that we can use to solve for x

We know use that equation to solve for x

2x + 20 = 3x - 15

add 15 to both sides

2x + 35 = 3x

subtract 2x from both sides

35 = x

And we are done!

One person can do a certain job in 20 minutes and another person can do the same job in twenty eight minutes. how many minutes w
Mamont248 [21]
I'm terrible at math, so I'm sorry if I'm totally wrong, but I'm assuming you just take the average:

20+28=48m
48/2=24m

On average, it may take them 24m if they work together.
