Question

Find the value of y.
Find the value of x.

Answer 1

What kind of triangle is this?

Answer 2

If it's equilateral or isosceles it can be easily solved.

Answer 3

I think it is a isosceles triangle

Answer 4

well, according to the diagram, 3x + 11 = 5x - 8 and 4y - 7 = 2y - 1

can you find the x and the y from this?

Answer 5

Okay. In that case you know that the two sides opposite of each other must be the same. Correct?

Answer 6

@Lunalovegood Can you do it?

Answer 7

So add the two sides individually together and solve the system of equations.

Answer 8

Solve for x: 3x + 11 = 5x - 8

Solve for y: 4y - 7 = 2y - 1

Answer 9

put each congruent side equal to each other.. notice the ones with the x values are congruent... same with the y values.. so you'll get 2 equations, one with x and one with y... solve an you will get ur x and y values :)

Answer 10

Ohh, yeah you could do that. too :P .

Answer 11

x=9?

Answer 12

I got 9.5.

Answer 13

let me re-check

Answer 14

yeah 9.5

Answer 15

Note that it is not an isoceles triangle, one side is 79 where x=9.5 and the other side is 10 where y=3.

Answer 16

Yeah. I made a bad assumption.

Answer 17

ahh i understand

Answer 18

the little red hash marks indicate what is equal and you were able to solve by equating the equal bisectors of the sides.
