Find the expression that represents the length of the hypotenuse of a right triangle whose legs measure 2x to the power of 2 - y to the power of 2 and to the power of 2xy

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

part a: 1.08

part b: 27.59

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
