Question

I can't seem to figure it out lol.​

Answer 1

Answer:

Step-by-step explanation:

Well looking at your triangle, it looks like an isosceles triangle since there to congruent sides.

2x+y=79-x

so x=-1/3y+79/3

and y=-3x+79

we can substitute the values of y and x

-1/3(-3x+79)+79/3=x

-3(-1/3y+79/3)+79=y

this sucks then the answer is all real numbers are the solution

let's try a different way to solve this...

A triangle is 180 degrees so

(4y+)(2x+y)+(79-x)=180

x=-5y+101

y=-1/5x+101/5

substitute the values of x and y

Answer 2

4y+2x+y+79-x=180°

5y+x=101

X=101 -5y
