Question

Find the missing side length of the right triangle

using the Pythagorean Theorem or PT converse.
A) 32 cm
B) 21 cm
C) 73 cm
D) 56 cm

Answer 1

33^2 + x^2 = 65^2
1089 + x^2 = 4225
1089-1089 + x^2= 4225-1089 (subtract both sides)
x^2 = 3136
x = 56cm

Answer 2

The answer is D) 56 cm

Explanation:

Using the Pythagorean Theorem, you would first have to multiply 65 x 65 to get 4225 and multiply 33 x 33 to get 1089. Then, for the last step, you will have to solve this little equation: 4225= 1089 +? To do this, you will have to subtract 4225 - 1089 = 3136. Finding the square root, you will finally get your answer of 56 cm.
