Please help i’m stuck!!<br> FIND GE AND FJ<br> HE = 6<br> FE= 8
dexar [7]

Answer:

GE=10

FJ=5

Step-by-step explanation:

We know that in a traingle

a^{2}+b^{2}  =c^{2}

a=HE=6

b=FE=8

Once we enter it into the equation, we find that we get

36+64=100

The square root of 100=10

GE=HF so HE=10.

Half of HE(10) is FJ(5)

Hope this help :)

Answer:

x-intercept (3 ,0)

y-intercept ( 0, –4)

<h3>Step-by-step explanation:</h3><h3 />

12x-9y=36 —> 12x-9(0)=36 —> 12x=36

x=36/12 —> x=3 —> So (x,y)=(3,0)

12(0)-9y=36 —> -9y=36 —> y=36/-9

y= –4 —> So (x,y) =(0,–4)

I hope I helped you ^_^
