First notice that the triangle with sides

and the triangle with sides

are similar. This is true because the angle between sides

in the smaller triangle is clearly

, while the angle between sides

in the larger triangle is clearly

. So the triangles are similar with sides

corresponding to

, respectively.
Now both triangles are

, which means there's a convenient ratio between its sides. If the length of the shortest leg is

, then the length of the longer leg is

and the hypotenuse has length

.
Since

is the shortest leg in the larger triangle, it follows that

, so
Step-by-step explanation:
-6+8=2 by -6 will cut from 8 and remain 2.
2+8=10 by same way 8 will added to 2 and got 10.
I hope it will help you

Answer:
48
Step-by-step explanation:
x = -2 y =3
3x² - 2xy²
3(-2)² -2(-2)(3)²
square first
3*4 -2(-2)*9
multiplty from left to right
12-2(-2)*9
multiply from left to right again
12 -(-36) subtract using rule for integers that double minus is plus
12 + 36
48
