Points plotted and connected
You can use the pythagorean theorem. Make sure that you put the measurements in the right places though. Since 11 is the measure of the hypotenuse, 11 has to be c. When you plug in the information that you have, it should look like this:
8^2 + b^2 = 11^2
Square 8 and 11.
64 + b^2 = 121
Subtract 64 from 121
121 - 64 = 57
The new equation is:
b^2 = 57
Now take the square root of both sides to get b by itself.
b = about 7.5
Answer: The height of the triangle is 7.5

Answer:
a) (2.64 -2/9 -0.35 +5/8)/4
b) perform the sum, then the division, then round as needed
Step-by-step explanation:
a) The average of a number of items is their sum, divided by the number of items. Here, we want the average of 4 changes, so we compute it as the sum of the changes divided by 4.
average change = (2.64 -2/9 -0.35 +5/8)/4

b) My calculator is capable of adding these numbers directly. For a result rounded to the nearest hundredth, it can be a good idea to represent the fractions using at least 3 decimal digits.
So, the steps would be ...
- convert fractions to their decimal equivalents, using 3 decimal digits
- add up the values
- divide by 4
- round to hundredths
Performing these steps, we get ...
average change = (2.64 -0.222 -0.35 +0.625)/4 = 2.693/4
average change ≈ 0.67 . . . degrees
The average daily temperature change of a city was 0.67 degrees.
NO! It has to be EXACTLY 90 degrees RIGHT of the triangle
