a. 3/4√3
b. 1/2√3
c.5/4√3
d.0

a.

Step-by-step explanation:

2√3/16 - √75/16 + 2√27/16

2/4√3 - 5/4√3 + 6/4√3

3/4√3

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
