Answer:
The angles are: 25°, 25°, 155° and 155°.
Step-by-step explanation:
1. By definition, the intersection of two lines forms four angles. Each opposite pairs of them are known as "Vertical angles" and they are congruent, which means than they have the same measure.
2. The sum of the four angles is 360°.
3. If the sum of the two angles is 50°, you can calculate the measure of each one of them by dividing 50° by 2:
4. To find each measure of the other two angles, you must subtract 360° and 50° and divide this by 2:
Answer:
2,100 miles
Step-by-step explanation:
we know that
On a map, the distance between Shanghai and Mount Everest measures 4 1/5 inches
<em>Convert mixed number to an improper fraction</em>
The scale of the map is 1 inch equals 500 miles
so
using proportion
Find out how many miles apart are Shanghai and Mount Everest
Let
