Robin has to go shopping for her brother's birthday.
She already bought "x" presents for him.
The next day, Robin bought "2" more presents for him just in time for his birthday.
When she got home and celebrated his birthday, her beother opened, in total, "9" presents.
--- What is the number of presents that Robin had originally purchased? ---
The answer is True. In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
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.
