Find the value of x

3. kirbykirby

The angle of a flat angle is 180. So, where you the the 110 angle... that means the angle on the inside (just on the other side of the 110) is 180-110 = 70 Since the sum of angles inside a triangle is 180, the remaining angle x is equal to 180-(70+72)=38

4. kirbykirby

x=38

6. Ammarah

So x equals 38 right?

7. Ammarah

Help

Yes, x = 38.

10. kirbykirby

Yes, triple confirming lol.

What is the third congruence needed to prove that triangle PQR is congruent to triangle STU using the indicated theorem?

13. kirbykirby

Oh my this is really farr back for me... I don't even know what HL or AAS mean? But I'm guessing AAS is like angle-angle-side o_O I don't know I didn't go to an English high school.

14. Ammarah

yes do u think its aas?

15. kirbykirby

What's HL??

16. Ammarah

Hyptotenuse leg its just like a right angle with two congruent sides

17. kirbykirby

I'm gonna guess with AAS.. it's the only thing remotely that I remember associated with congruences

18. Ammarah

Help with rotations, reflections, and translation

It's kind of a trick question. It's a right triangle, so you could argue HL (which is actually a special case of SAS) since you're given the hypotenuse and just need a leg. But it's also AAS since you're given an angle and a side. I would probably go with HL and, unless a computer is grading, write a note that says you could also prove it with AAS.

20. ChristianGeek

They should have made ASA the second option, in which case it definitely would have been HL (because the hypotenuse wouldn't be the side between the two angles).
