Question

Can anyone help me ?.....
Look at the two triangular sign boards below.



Which pair of equations is correct?

x = 62 and y = 6

x = 38 and y = 9

x = 1 and y = 8

x = 45 and y = 69

Answer 1

How far did you get?

Answer 2

uhh Ithink its b buh im not shur

Answer 3

It's not. Both triangles are congruent by AAS. You can tell this by the congruent angles and the side it gives you. If the triangles are congruent then the sides are equal. set up your 2 equations and solve. Hint: solve for x first if you get it right you don't have to solve for y because you'll know what letter is is

Answer 4

so how do u solve it ?

Answer 5

match up the corresponding sides between the 2 triangles and set them equal then solve for the missing variable

Answer 6

is it (8y-3) and (x-7) the corresponding sides ??

Answer 7

Since the triangles are congruent, their sides are equal. Set a side from triangle 1 equal to the same (corresponding) side on the other triangle.

Answer 8

buh answer d shows the same x n y so tht cant be it ?

Answer 9

8y - 3 = 45
x + 7 = 69

Answer 10

good deduction. that is correct

Answer 11

wait ! so they want u to find x n y ? so its c ??

Answer 12

yes they want you to solve for x and y. so you need to solve for them using the 2 equations I gave you. I got these from matching up the sides since they are equal

Answer 13

so its c ?

Answer 14
