The correct answer is 95°.

To solve for n, you can start by finding the measures of the triangle's interior angles. Knowing that a straight line measures 180°, you can subtract the given values from 180° to find the measures of the respective supplementary interior angles. That would give you 59° (180-121) and 36° (180-144).

Now, knowing that the measure of all the interior angles of a triangle is also 180°, you can add the two interior angles you know (59+36) and subtract those from 180°. Doing so would give you the measure of the missing third angle, which is 85°.

Finally, because angle n is the supplementary angle of the missing angle from the previous step, simply subtract that angle's measure from 180° to find n°, which is 180-85 or 95°.

Which of the following pairs of items is a better​ buy?
Bas_tet [7]

Answer:

a. 6Pack of paint brushes for $12.99

b. 5 classes for $64.99

c. 12 pack of paper plates

Step-by-step explanation:

a.

I could buy a 6 pack of paint brushes for $ 12.99

or

buy 6 individual brushes for the price of $ 2.19 each.

6 x $2.19 = $13.14

first option is cheaper

b.

10 classes for s total of $150

$150 ÷ 10 = $15 (price per class)

5 classes for $64.99

$64.99 ÷ 5 = $12.998 (price per class)

c.

12 pack of paper plates for $2.29

25 pack for $4.99

$2.29 ÷ 12 = $0.1908 (price of one plate)

$4.99 ÷ 25 = $0.1996 (price for one plate)
