Find the measure of angle A.<br><br> 71° x+49<br> +72

slega [8]

Answer: 66 degrees

Step-by-step explanation:

Sum of the angle measures is 180, so:

71 + x + 49 + x + 72 = 180

2x + 192 = 180

2x = -12

x = -6

Meaning the measure of angle A = -6 + 72 = 66 deg.

Please help I’ve been stuck on it forever. :(

Answer:

$31.37 is the sale price

Step-by-step explanation:

All you need to do to find the discount price (sale price) is multiply the price of the item by the decimal form of the percentage.

1. Store A. 40% off the original price of $159.99

$(159.99 * .40) = 63.996$

63.996 is the discount price we are looking for

2. Store B. 25% off the original price of $130.50

$(130.50 * .25) = 32.625$

32.625 is the discount price we are looking for

3. Now to find their difference you just subtract the two values.

$($63.996 - $32.625) = $31.371$

The discount price (sale price) is $31.371
