Victor had 321.8 dollars, andrey had 15.8 dollars more than victor had. david had 5 times less than victor and andrey had together. how many dollars did each boy have?

Step-by-step explanation:

Andrey had $321.80 +15.80 = $337.60.

We assume "5 times less than" means "one-fifth of", so David had ...

  (1/5)($321.80 +337.60) = $131.88

The amount each had was ...

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
