21. reynaldo is on the beach playing catch with his dog, rex ruthor. when reynaldo tosses the ball into the
water, rex races down the shore, then dives into the water and swims to the ball. rex can run 10 feet per
second and swim 2 feet per second. reynaldo tosses the ball into the water so that it lands 6 feet from the
shore and 38 feet along the shoreline. if it takes rex a total of 8 seconds to get to the ball, how far along
the shore did he run before diving in?
38 feet

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

meaning of term low   inflation is when prices of commodities does not change very highly.so low inflation is   not a sign of healthy economy.the demand of goods becomes higher due to some faulty measures taken by government

there are two kind of inflation

1. positive inflation : when supply of goods is less than prices of those goods rise.

2. negative inflation : when supply of any good is very high so it,s price will fall.

so option c is true : struggling economy because it results from a steady rise in demand.
