Use linear pairs to find the measure of angle B and the measure of the angle adjacent to the measured angle 135. Use the vertical angle theorem to find that angle inside the triangle across from B. Then use the triangle angle sum theorem to add up your values to equal 180. Solve for x and then plug that value back into 31 +x.
The distance between Pittsburgh and Cleveland is 200 miles
<u>Solution:</u>
Given that,
Plane travels from Pittsburgh to Cleveland in 2 hours
Average speed of plane = 100 miles per hour
<em><u>To find:</u></em> Distance between these two cities
<em><u>The relation between speed distance and time is given as:</u></em>

On rearranging the above formula, we get

Distance between these two cities = 

Thus both the cities are 200 miles apart
Answer:
(a) Mean = 587
Median = 585
Mode = 590
Standard deviation = 112.54
(b) Mean and median are both appropriate as they are close in value, suggesting that the data is quite symmetric.
Explanation:
All four measures are calculated by inserting simple formulas in Excel. These are shown in the below screenshot of the work file.
