Question 11 of 20 select the best answer for the question.
11 what is the length of missing side b in the figure below?
7 cm
13 cm
a. v120 centimeters
b. v91 centimeters
c. 218 centimeters
d. v6 centimeters

The side b is called base of the right triangle, the 7 cm side is the height, and 13 cm is the hypotenuse. We can get the value of b by applying Pythagoras formula, which is b² + 7² = 13 ², and then b² =169 – 49 = 120, from where we get b= sqrt(120). Finally the true answer is A. V120 centimeters
