Question

I am willing to do the work. I want to learn. I will include document once the question becomes open. Furthermore, I want to learn. I would like to contribute to the answer in anyway possible. If we could work through it together I would highly appreciate it.

Answer 1

lemme see

Answer 2

X is the obtuse angle

Answer 3

obtuse angles are >90

Answer 4

i guess they mean this

Answer 5

and of course is it <180 because 180 is the sum of all angles

Answer 6

hmm wait lemme think

Answer 7

If this helps the lesson is called: "Isosceles triangles and Corresponding Parts". I don't thing it can below 90°, because as you mentioned it's obtuse. It can't be 180° because again as you mentioned that is the sum of all angles.

Answer 8

yeah

Answer 9

I can name of a couple of postulates if that helps...

Answer 10

@jigglypuff314 what do they mean?

Answer 11

waittttttttttttttttttttttttttt

Answer 12

i got it

Answer 13

An equilateral triangle has the same angle measure for all 3 angles

you need to find x only
180 - 60 = x

Answer 14

yeah mehek beated me

Answer 15

:P

Answer 16

do you know that the angles of equilateral triangles is 60 degrees each?

Answer 17

x+60=180

just solve for x

lol

Answer 18

... yep xD then "linear angle" where the two angles add up to 180 degrees

Answer 19

A reasonable answer could be 120° could it not. Ah, yes of course because of corollerly 1.

Answer 20

y is just there
you dont have to worry about it
and yes
120

Answer 21

lol yeah

Answer 22

May I ask another question?

Answer 23

of course

Answer 24

The other question is based off the EXACT same graph, but asks the value of y. The answers are the same: 60, 120, 30, 180. It can't be 180 because that is the sum of a triangle. It can't be 120 because the x angle is clearly larger. That leaves 60 and 30. Based on the previous comments I believe the answer is 30°. If not please let me know. I want to learn!

Answer 25

180 - 120 = ?

Answer 26

since it is an isosceles triangle, y and the other unknown angle are equal

Answer 27

I truly love to over complicate things in math, based on the previous comment the correct answer is 60°.

Answer 28

180 - 120 = 60
correct
but y is not 60
