What is the missing sum of 8/9= /54

The missing sum is 48

Step-by-step explanation:

Assume the missing sum is x

The equation can be rewritten as

8/9 = x/54

By cross multiplying, we will have

9 × x = 8 × 54

9x = 432

Divide both sides by 9

x = 432/9

x = 48

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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
