To determine the hypotenuse, use the formula a^2 + b^2 = c^2.
Place 80 as "a" and 39 as "b". Your formula should look like 80^2 + 39^2 = c^2.
Next, plug this into your calculator to get 7921. Then square root 7921.
Answer: 89
Answer:
20x = 55
Step-by-step explanation:
First you have to add 3x to both sides of 11-3x=x
Now that you have 11 = 4x you divide 4 on both sides
11/4 = x
But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75
so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55
Wdym? Can you be more specific?
