Addy bought a new shirt and she had a 20% off coupon . The coupon took $8.25 off of the price of her shirt. What did she pay wit
zloy xaker [14]

Answer:

$33

Step-by-step explanation:

Given: Addy had 20% off coupon.

           The coupon took $8.25 off of the shirt price.

Lets assume the original cost of shirt be "x".

We know Addy had 20% off coupon, which help to reduce the price of shirt by $8.25.

∴ We can form an equation to know the original price of shirt.

⇒\frac{20}{100} \times x= \$ 8.25

⇒\frac{1}{5} \times x= \$ 8.25

Multiplying both side by 5

⇒x= 8.25\times 5

∴ x= \$ 41.25

Hence, The original cost price of shirt was $41.25.

Next, finding the price paid by Addy for her new shirt by reducing coupon discount from the cost of shirt.

Price paid by Addy for her new shirt= \$ 41.25- \$ 8.25= \$ 33

Hence, Addy paid $33 for her new shirt.

Given that LM and LN are tangent to the circle and that the measure of angle MLN = 75.86, find the measure of arc MN.
siniylev [52]

we know that

The measure of the external angle is the semidifference of the arcs that it covers

so

∠MLN=(1/2)*(mayor arc MN-minor arc MN)

Let

x------> minor arc MN

major arc MN=360-x

substitute in the formula above

∠MLN=(1/2)*(mayor arc MN-minor arc MN)

75.86=(1/2)*(360-x-x)------> 151.72=(360-2x)------>360-151.72=2x

x=104.14°

therefore

the answer is

the measure of arc MN (minor arc) is 104.14°

Lyrx [107]

Answer:

133.45

Step-by-step explanation:

They are looking for arc length. The formula is

\frac{n}{360} * 2πr

a quarter circle is 90°, so put 90 for n. 85 is the radius, so put that for r.

\frac{90}{360} * 2 π (85)
