## TashaMeni7 Group Title 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. one year ago one year ago

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

2. TashaMeni7 Group Title

Thanks.

3. karama Group Title

A should equal 60, intersection and all that

5. TashaMeni7 Group Title

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

6. karama Group Title

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 Group Title

that;s not right saw my error

8. karama Group Title

vertical angles are equal

9. jazy Group Title

That's true^

10. karama Group Title

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

11. TashaMeni7 Group Title

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 Group Title

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 Group Title

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

14. jazy Group Title

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

15. jazy Group Title

Nope. You're completely right @karama (:

16. TashaMeni7 Group Title

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

17. karama Group Title

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

18. TashaMeni7 Group Title

Sure thing.

19. TashaMeni7 Group Title

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 Group Title

The same triangle?

21. TashaMeni7 Group Title

Yes.

22. karama Group Title

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 Group Title

ohhh..Okay I understand that.

24. karama Group Title

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

25. karama Group Title

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

26. TashaMeni7 Group Title

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