Answer:

1. complementary

2. neither

3. supplementary

4. complementary (x = 6)

<em>10x + 30 = 90         x + 3 = 9          x = 6</em>

5. supplementary (x = 20)

<em>4x + 40 + 3x = 180       7x = 140       x = 20</em>

6. x = 50.5

<em>2x + 79 = 180     2x = 101       x = 50.5</em>

Step-by-step explanation:

When the measurement of the angles adds up to 90 degrees, the angles are complementary. When the sum of the angles is 180 degrees, then they are supplementary.

Answer:

supplementary angles - two angles are supplementary when they add up to 180 degrees (a straight line)

complementary angles - two angles are complementary when they add up to 90 degrees (a right angle)

hopefully this helps! :)

Cities A &amp; B are 5 inches apart on a map. Cities Ce Dare 4 inches apart. If C &amp; D are 900 miles apart how many miles apa
Afina-wow [57]

Answer:

<u>Cities A and B are 1,125 miles apart</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Distance between A and B in the map = 5 inches

Distance between C and D in the map = 4 inches

Real distance between C and D = 900 miles

2. How many miles apart are cities A and B?

We will solve the question, using Direct Rule of Three, as follows:

Distance in the map      Real distance

A - B     5 inches                    x

C - D     4 inches                900 miles

***************************************************

4x = 900 * 5

4x = 4,500

x = 4,500/4

x = 1,125 miles

<u>Cities A and B are 1,125 miles apart</u>
