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 :)
