Guest (Customer)
[00:00:00] i need to type it

Anne S (Tutor)
[00:00:23] Hello. Welcome to tutor.com . How can I help you?

Guest (Customer)
[00:01:12] finsihed

Anne S (Tutor)
[00:01:40] ok. so you have two angles that you are working with. Do you know what their relationship is?

Guest (Customer)
[00:02:01] they both equal

Anne S (Tutor)
[00:02:23] good. so if they are equal, we can set the two expressions equal to each other.
[00:02:52] now you just need to solve it.
[00:03:00] careful
[00:04:05] good.
[00:04:10] careful
[00:04:24] when you move the x over you need to use the opposite operation
[00:05:03] yes
[00:05:44] ok so x is 15, what is the measure of the angle?

Guest (Customer)
[00:06:29] i don't kniow

Anne S (Tutor)
[00:06:47] the angle is x + 10 or 4x - 35

Guest (Customer)
[00:06:59] x+10

Anne S (Tutor)
[00:07:13] and x is 15, so what is the angle?

Guest (Customer)
[00:07:26] 25

Anne S (Tutor)
[00:07:36] excellent
[00:07:49] do you have any other questions?

Guest (Customer)
[00:08:01] yes another question i ahve to do

Anne S (Tutor)
[00:08:07] ok

Guest (Customer)
[00:09:02] fin sieghd
[00:09:06] finihsed

Anne S (Tutor)
[00:09:13] is that a 4y in the lower one?

Guest (Customer)
[00:10:03] yes

Anne S (Tutor)
[00:10:28] ok. well this one has two steps. the first is the same as the last example.
[00:11:32] careful
[00:11:55] good.
[00:12:06] careful again-- you need to do the opposite
[00:12:11] to move the x's
[00:12:40] you cant move them all to one side
[00:12:56] you need to move the 5x over
[00:14:30] good
[00:15:16] so what is that angle when you plug in x?

Guest (Customer)
[00:15:36] 5x=4y
[00:15:41] 5x+4y

Anne S (Tutor)
[00:15:53] plug 14 into 3x + 8
[00:17:04] what is the relationship between these tow angles?
[00:18:01] lets get a clean board to finsish this on
[00:19:00] what is the relationship between these two angles?
[00:20:08] we need to know what 70 + 4y equals
[00:20:14] we can't solve yet
[00:20:41] two angles that together make a straight line have what relationship?
[00:21:30] they are not equal
[00:21:35] they are supplementary
[00:21:58] so if the smaller one is 50, what is the larger one?
[00:22:57] are you there?

Guest (Customer)
[00:23:05] yes i don't know

Anne S (Tutor)
[00:23:17] what are supplementary angles?

Guest (Customer)
[00:23:43] 180

Anne S (Tutor)
[00:23:55] ok so one is 50, what is the other?

Guest (Customer)
[00:24:22] 180

Anne S (Tutor)
[00:24:41] the two have to add to 180
[00:24:48] so 50 plus what is 180?

Guest (Customer)
[00:26:18] 175

Anne S (Tutor)
[00:26:31] that ist 180 - 5 not 180 - 50
[00:27:21] good so 70 + 4y = 130
[00:27:30] now you can solve for y
[00:28:49] I got it! Thanks!
[00:28:57] sorry you got it
[00:29:11] Do you have any questions about anything we went over today?
