Question

PLEASE HELP :) DIAGRAM BELOW
use the marked parallel lines to find the value of y in the diagram below (1 point) a. 19 b. 50 c. 55 d. 18

Answer 1

I will give a medal!!!!!!

Answer 2

@GoldPhenoix please help

Answer 3

Do you know the relationship between angle measurement (2x+5) and angle measurement (3x-45) ?

Answer 4

umm are they alternate exterior angles?

Answer 5

im so consused :0

Answer 6

Not quite. They're actually alternate interior angles, since they're angles inside the z-like shape. Since they're alt. interior angles, then they have the same angle measurement.

So write an equation:
(2x+5) = (3x-45)
Now find x. :)

Answer 7

okay one sec

Answer 8

x= 50

Answer 9

Alright. So the angle measurement of each is 50 degree.

Answer 10

okay

Answer 11

Now wait 1 minute. >_>

Answer 12

wutt

Answer 13

There's more. :)
But I have to see if my next step is correct.

Answer 14

lol okay

Answer 15

I see. You have to add a few more steps. The parallel line and the 2 transversal makes a 4-sided shape. Now how many degree does a 4-sided shape have?

Answer 16

I am not sure.... im really bad at math

Answer 17

Well, you can use the formula 180(x-2) to find the degree of any interior angle.
Let x = the number of side that shape has.
180(4-2) = 360.
So we already have 1 clear side, 50 degree.

Answer 18

Nowe we need to find the other 3 side angle.

Answer 19

So what's A?

Answer 20

130

Answer 21

Good.
