Question

If triangleABC is congruent triangleXYZ, find angle Y. *picture included in comments

Answer 1

Have you tried it out yet?

Answer 2

i have no idea how to do this one at all

Answer 3

Corresponding angles of congruent triangles are congruent.

Answer 4

well, i would assume that? i don't know where the m is coming from.

Answer 5

m means measure

Answer 6

Well it looks like angle X is equal to angle A correct?
And Angle Z is equal to angle C

and finally angle Y equal to angle B

So if you look at all the angle you have...we have



we have 2 angles of a triangle....and a triangles angles add to 180....so what is that missing angle?

Answer 7

oo 80?

Answer 8

Asking me or telling me? :)

Answer 9

both lol

Answer 10

Haha yes 80 is correct :)

Answer 11

Given that triangleXYZ triangleNML, mangX = 20°, mangM = 75°, and mangL = 5(w – 2)° , find the value of w.
do i make this add up to 80 too?

Answer 12

and if you got all those question marks idk where they came from haha

Answer 13

Lol it's a bug that has been affecting Openstudy for a little bit

But in general...yes all internal angles of a triangle add up to 180...it's a good way to make sure you're on the right track :)

Answer 14

so the answer would be 80, correct?
20+75+5(85-2)=180

Answer 15

or waiiit 19-2

Answer 16

Wait? why would it be 80?

so we add them all up yes

20 + 75 + 5(w - 2) = 180
95 + 5(w - 2) = 180
5(w - 2) = 85
5w - 10 = 85
5w = 95
w = 19

:)

Answer 17

okay thanks :)

Answer 18

Anytime :)
