Question

The lengths of the legs of a right triangle are 12 cm and 16 cm. What is the length of the hypotenuse? 4 centimeters 20 centimeters 22 centimeters 28 centimeters

Answer 1

The answer is C, 20 centimeters

Answer 2

so pythagorean theorem
a^2+b^2=c^2
a and b are legs
c=hypotonuse

legs=12 and 16
subsitute
12^2+16^2=c^2
144+216=c^2
400=c^2
squareo root both sides
20=c
hypotonuse=20 cm
