Triss [41]3 years ago

The answer is 39% though the actual answer was 38.67. I guess it's supposed to be approximated???
Anyways, here is my working:
First, add all the amounts of families with an annual income of over $60,000:
63+70+32+16= 181 (total)
Then, take the amount of families who might or might not purchase a newspaper subscription which is 70, and total it on the total which is 181 over 100 to find the %:
70/181×100 = 38.67 (approximated to 39%)
Hope this helps!!!!!

Dana draws a triangle with one angle that has a measure of 40∘.
OLEGan [10]

Answer:

140°

Step-by-step explanation:

<u>Given:</u>

Dana draws a triangle with one angle that has a measure of 40∘.

<u>Question asked:</u>

What is the measure of the angle’s adjacent exterior angle?

Solution:

<u>As we know:</u>

<u><em>Sum of the adjacent interior and exterior angles is 180°.</em></u>

Interior angle = 40°

Adjacent exterior angle = ?

Interior angle + Adjacent exterior angle = 180°

40° + Adjacent exterior angle = 180°

<u>By subtracting both sides by 40°</u>

40° - 40° + Adjacent exterior angle = 180° - 40°

Adjacent exterior angle = 140°

Therefore, the measure of the angle’s adjacent exterior angle will be 140°.
