Hypotenuse is the side opposite the right angle in a right triangle. It is the longest side of a right triangle.
A. 16.5 units
B. 5.0 units
C. 8.5 units
D. 6.5 units
Correct Answer: A
Step 1: From the figure, a = 3.9 and b = 5.2.
Step 2 :c2 = a2 + b2[Apply Pythagorean theorem.]
Step 3: c2 = 3.92 + 5.22 [Substitute for a and b.]
Step 4:c2 = 15.21 + 27.04 = 42.25
[Apply exponents and simplify.]
Step 5: [Take square root of both sides and simplify.]
Step 6: The measure of the hypotenuse, c = 6.5 units.
