Answer:
P=4.5
Step-by-step explanation:
Area of DFH is area of GFD minus area of GHD.
Area of GHD:
GH^2=5^2-3^2=16
GH=4
P1=4*3/2=6
Area of GFD:
P2=7*3/2=10.5
Area of DFH
P=P2-P1=10.5-6=4.5

Answer:
<h2><u>
x = 8.2</u></h2>
Step-by-step explanation:
A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.
First triangle on the right:
5^2+B^2=10^2
25+B^2=100
B^2=75
B=8.66025404
B=8.7
Second triangle of left:
3^2+B^2=8.7^2
9+B^2=75.69
B^2=66.69
B= 8.16639455
B=8.2
x=8.2
