What is the value of x?

Step-by-step explanation:

For resolve this problem I use trigonometry identities.

Where is the angle of the triangle (45), is the opposite side of the angle () and the is the hypotenuse ().

Replace the know values in the relation

Isolate of the equation and solve

So the final answer is

6 and 24

step-by-step explanation:

6 x 4 = 24

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
