## TashaMeni7 2 years ago HElp me Out? 1. What is the degree measure of angle A? __________ degrees http://www.flickr.com/photos/63839927 @N04/8219196862/in/photostream/lightbox/ 2. What did you use to find the measure of angle A? (1 point) A. 60 + x + A = 180 B. 180 – 150 = A C. Interior angles are equal D. Vertical angles are equal Have to copy and paste the whole link.

i don't know...I can upload it somewhere else.

2. TashaMeni7

Thanks.

3. karama

A should equal 60, intersection and all that

5. TashaMeni7

So your saying it equals 60 and number 2 is ???

6. karama

I'd go with the interior angle answer,...if I remember correctly, it means the same thing as saying " opposit angles are equal"

7. karama

that;s not right saw my error

8. karama

vertical angles are equal

9. jazy

That's true^

10. karama

meaning that A= 60 because it is an angle of intersecting lines, aka A=60 because they are vertical angles

11. TashaMeni7

Ohh..so did you just solve those equations then subtracted it?? I'm trying to understand I'm just not good with Geometry.

12. karama

What I did was make an inference based off of vertical angle theorem. If there are two lines that intersect, then they will create four angles. Each angle has an opposing angle, vertical from its perspective. The two opposite or vertical angles are equal

13. karama

Jazy seems to have a more current handle on geometry than me, so correct me if any of that is innacurate

14. jazy

Vertical angles are equal. ex: |dw:1353898300187:dw|

15. jazy

Nope. You're completely right @karama (:

16. TashaMeni7

^^^ I understand that with the pic..thanks guys. :))

17. karama

you're welcome...let us know if you have any other questions! :)

18. TashaMeni7

Sure thing.

19. TashaMeni7

Can I have help with finding the degree of x? and Which of the following can you use to find the degree measure of angle x? 180 – (60 + A) = x 150 – 60 = x x = 60 + A x = 150 – 50 180 – 90 = x These are my last questions that I need help with.

20. jazy

The same triangle?

21. TashaMeni7

Yes.

22. karama

let's see, it might be 90...because y=30, since 180-150=30...then 60+30=90...triangles must have angles that sum to 180...180-90=90

23. TashaMeni7

ohhh..Okay I understand that.

24. karama

$180=\alpha+\beta +\gamma$ each symbol represents an interior (meaning inside of) angle of a triangle

25. karama

|dw:1353899048358:dw| as well, in case you need any reference for how I got the value of Y

26. TashaMeni7

Yeah.. I'm understanding it..Thanks again.
