Finding angle A is the easiest. Do you know what vertical angle theorem states?

- anonymous

no? lol im trying to find a,b, and c i need all 3 of them

- anonymous

|dw:1436300517263:dw|

- anonymous

okay so how do i find the angles

- anonymous

|dw:1436300695260:dw|

- anonymous

What do you think is angle A based on what I drew?

- anonymous

35 since a and b are congruent?

- anonymous

Yes.

- anonymous

Did you see the square symbol in the triangle where angles a and b are located?

- anonymous

Do you know what that symbol means?

- anonymous

no

- anonymous

equalt too?

- anonymous

It means it is a right triangle.

- anonymous

|dw:1436301015357:dw|

- anonymous

If it is a right triangle, the it means it is 90 degrees, correct?

- anonymous

|dw:1436301083058:dw|

- anonymous

Now, how many angles are there (in total) in a triangle?

- anonymous

3

- anonymous

That's the side.

- anonymous

idk angles

- anonymous

You should know that there are 180 degrees in a triangle.

- anonymous

|dw:1436301326913:dw|

- anonymous

to find b, add the angles together then subtract them from 180.

- anonymous

angle b**

- anonymous

|dw:1436301606362:dw|

- anonymous

You know how to do the math, don't you?

- anonymous

yea 125

- anonymous

:(

- anonymous

WHat is 35 + 90?

- anonymous

125

- anonymous

WHat is 180-125?

- anonymous

55

- anonymous

so c is 55?

- anonymous

No, b is 55.

- anonymous

|dw:1436302097297:dw|

- anonymous

For angle C, use the supplementary angles theorem.

- anonymous

supplementary means two angles are equal to 180.

- anonymous

|dw:1436302182333:dw|

- anonymous

okay

- anonymous

Do you now know how to get angle C? :)

- anonymous

ik i have to add with the 70

- anonymous

Yes, so...
\[

- anonymous

110?

- anonymous

Then that's it. :)

- anonymous

okay so what was a than ;(

- anonymous

Yes. :) Great job!

- anonymous

what than?

- anonymous

what was (a)

- anonymous

Angle A?

- anonymous

You already answered that. Look up.

- anonymous

Scroll up our conversation. That's the first thing we did. :/

- anonymous

35 i think

- anonymous

And I said "yes," right? :)

- anonymous

pretty sure :)

- anonymous

It's 35 because of the Vertical Angle Theorem.

- anonymous

okay okay thanks

- anonymous
