Question

Which value is closest to the unit length of GF in the coordinate plane below ?

Answer 1

Answer:

$GF=11\ units$

Step-by-step explanation:

we know that

Applying The Pythagorean Theorem in the right triangle GHF of the figure

$GF^2=GH^2+HF^2$

we have

$GH=6\ units\\HF=9\ units$

substitute

$GF^2=6^2+9^2$

$GF^2=36+81$

$GF^2=117$

$GF=10.8\ units$

Round to the nearest unit

$GF=11\ units$
