He price of a pair of earrings is $22 but Priya buys them on sale for $13.20.

What was the percentage of the discount?

Priya enjoyed a 40% discount

Step-by-step explanation:

The key information in the question:-

*** The normal cost of a pair of earrings is $22

*** Priya eventually purchased the pair of earrings for only $13.20

*** We are required to calculate the percentage discount.

Discount generally refers to the reduction from the usual price of something. In this scenario, since Priya bought the pair of earrings for only $13.20 instead of the usual $22, the discount that Priya enjoyed =

$22.00 - $13.20

= $8.8

To calculate the percentage discount that Priya enjoyed, we divide the discount by the normal price and then multiply the result by 100

= (8.8/22) × 100

= (88/220) × 100

= 0.4 × 100

= 40%

Therefore, Priya enjoyed 40% discount on the price of the pair of earrings.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
