Let,
12x + 15y =34--------(1)
-6x + 5y =3-------(2)
(2) x 2 = -12x + 10y =6-------(3)
(3) + (1)
20y =40
y= 2
substitute y=2 into (1)
12x + 15(2) =34
12x =4
x= 1/3

Answer:
x=45
Step-by-step explanation:
We know that this is a right isosceles triangle because it has a right angle (square) and a triangle has to add up to 180 degrees so 90+x+x=180
90+2x=180
2x=90
x=45
