The figure below shows two congruent triangular parks. What equation would help you to solve for the side length of BC and EF? Explain your reasoning using complete sentences. (8 points)

@3mar

@Will.H

OpenStudy (will.h):

Can't see the figure

OpenStudy (risingtotop):

oh yeah

OpenStudy (risingtotop):

OpenStudy (risingtotop):

EXCEPT the sides are 17 and 9 ! and the hypotenuse is 2x-3 and x+5

OpenStudy (will.h):

They are congruent figures which means BC = EF 3x - 4 =

OpenStudy (will.h):

3x - 4 = x + 6 Solve for x

OpenStudy (will.h):

Actually you just need the equation. And that's the equation Reasoning would be Since the triangles are congruent and we know that those sides are corresponding then BC = EF Hence 3x - 4 = x + 6

OpenStudy (risingtotop):

x=8

OpenStudy (risingtotop):

2x-3=x+5 ***********

OpenStudy (will.h):

Mate you solved incorrectly.

OpenStudy (will.h):

X would equal to 5

OpenStudy (will.h):

And you can find the measure of EF or the other side by substituting x = 5 in the expression

OpenStudy (risingtotop):

Mate... it's 2x-3=x+5 !!!

OpenStudy (risingtotop):

equals 8

OpenStudy (3mar):

It is 8, Will

OpenStudy (will.h):

3x - 4 = x + 6 That's the equation

OpenStudy (will.h):

Right?

OpenStudy (3mar):

Correct, don't get me confused :(

OpenStudy (risingtotop):

nooooo omg!!!!!!!!!! i said that those are the incorrect numbers and stuff

OpenStudy (will.h):

Either my equation is incorrect or yours And I'm seeing the attachment file that u posted and pretty sure those r the data

OpenStudy (3mar):

No, it is not like that. 3x - 4 = x + 6 wrong RisingToTop said: "EXCEPT the sides are 17 and 9 ! and the hypotenuse is 2x-3 and x+5"

OpenStudy (risingtotop):

the 2 triangle sides are 17 and 9 and the hypotenuse are 2x-3 and x+5

OpenStudy (will.h):

I didn't read that sorry Well then. Same solution just chang the equation

OpenStudy (will.h):

Good eye 3mar

OpenStudy (risingtotop):

x=8

OpenStudy (3mar):

Don't mention that! It Happens to all of us!

OpenStudy (3mar):

Correct! @RisingToTop

OpenStudy (will.h):

2x - 3 = x + 5 X = 8 To find tbe length of either sides use substitution method

OpenStudy (risingtotop):

thanks so much bruv's
