What is the hypotenuse of a right triangle if the legs are each 20 inches long? Round to the nearest whole number. A. 28 B. 29 C

marusya05 [52]

Answer:

The answer is A.

Step-by-step explanation:

You have to apply Pythagoras Theorem :

${c}^{2} = {a}^{2} + {b}^{2}$

$let \: a = 20,b = 20$

${c}^{2} = {20}^{2} + {20}^{2}$

${c}^{2} = 800$

$c = \sqrt{800}$

$c = 28 \: (nearest \: whole \: no.)$

P.S (Take note):

Pythagoras Theorem can only applied in right angle triangle.
