Answer:

DG=8.62

Explanation:

DG is also the hypotenuse. Use the sine ratio. Insert values:

$sineX=(opposite)/(hypotenuse)\\\\sin72=(8.2)/(x)$

Solve for x. Multiply both sides by x:

x*(sin72)=x*((8.2)/(x) )

x*sin72=8.2

Divide both sides by sin 72:

(x*sin72)/(sin72)=(8.2)/(sin72)

x=(8.2)/(sin72)

Insert into a calculator:

x=8.622

Round to the nearest hundredth:

x=8.62

Done.
