Answer:
Step-by-step explanation:
Let the other leg = x
x^2 + 4^2 = (3x)^2
x^2 + 4^2 = 9x^2
4^2 = 9x^2 - x^2
16= 8x^2
16/8 = x^2
x^2 = 2
x = sqrt(2)
The lengths of the sides
other side =4
hypotenuse = 3*sqrt(2)
x = 1.4
other side= 4
hypotenuse = 3*1.4142
hypotenuse = 4.2
x=4
where y =3x
8x-3x=20
5x=20
5x/5=20/5
I think it would be “B”
D) x = ± 2√5 - 4
2x² + 16x - 8 = 0
Yah, i plugged this into m a t h w a y
