What's the variable of x?​

Step-by-step explanation:

in right angled triangle ;

hypotenuse² =( side 1)² +(side 2)²

(65)²=(25)² +(x)²

4225 = 625 + (x)²

4225 - 625 = x²

3580 = x²

59.83 = x

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
