Question

Which pair of equations is correct?

x = 50 and y = 80

x = 2 and y = 30

x = 20 and y = 20

x = 1 and y = 60

Answer 1

@Kaitlyn_The_Math_wiz is there any relation between the two triangles?

Answer 2

they look almost similar or congruent i think

Answer 3

Yes they are congruent

Answer 4

so could you find any relation to find x and y?

Answer 5

oh its x=1 and y=60 right if the two triangles are congruent?!

Answer 6

yeah, you're correct :)
hod did you solve?

Answer 7

do what?

Answer 8

y+20 = 80
y = 80 - 20 = 60 I bet that is the way it was solved.

Answer 9

sorry * how

Answer 10

Being it has been decided the two triangles are congruent. (side, opposite angle)

Answer 11

30x + 20 = 50
30x =50 -20 =30
x = 1
