Question 32411: A right triangle is a triangle with one angle measuring 90°. In a right triangle, the sides are related by Pythagorean Theorem, c^2=a^2 + b^2 where c is the hypotenuse (the side opposite the 90° angle). Find the hypotenuse when the other 2 sides’ measurements are 3 feet and 4 feet.

a=3
b=4
+a%5E2+%2B+b%5E2+=+c%5E2+
plug a and b in
+3%5E2+%2B+4%5E2+=+c%5E2+
+9+%2B+16+=+c%5E2+
+25+=+c%5E2+
+5+=+c+
MEMORIZE these relationships:
3:4:5 or 6:8:10 or 9:12:15 etc
5:12:13
These are the most common of the right triangle relationships
