The length of the hypotenuse of a right triangle is 145 units. The length of one leg of the triangle is 144. Mike wrote the following step to find the length of the unknown leg:
Length of the unknown leg = 1452 − 1442 = 21,025 − 20,736 = 289 units
Which statement best explains whether Mike's step is correct or incorrect?

(Length of unknown leg)^2 =145^2 - 14^2
(Length of unknown leg)^2 =21,025 - 20736
(Length of unknown leg)^2 =289
Length of unknown leg = Square Root of 289
Length of unknown leg = 17
Therefore, the method is wrong because it did NOT take the square root of 289

thx man

(03.01 HC)
The length of the hypotenuse of a right triangle is 145 units. The length of one leg of the triangle is 144. Mike wrote the following step to find the length of the unknown leg:
Length of the unknown leg = 1452 − 1442 = 21,025 − 20,736 = 289 units
Which statement best explains whether Mike's step is correct or incorrect?
It is incorrect because the length of the unknown side is the square root of 289.
It is incorrect because the length of the unknown side is the square root of 41,761.
It is correct because the length of the unknown side is the difference of the lengths of the sides.
It is correct because the length of the unknown side is the difference of the squares of the sides.

Look at triangle ABC.
Coordinate grid shows negative 5 to positive 5 on the x axis and y axis at intervals of 1. A triangle ABC is shown with A at ordered pair 4, 5, B at ordered pair 2, 2, and C at ordered pair 4, 2.
What is the length of side AB of the triangle?
3
5
Square root of 6
Square root of 13

use the Pythagorean Theorem, I think

for these just remember a^2+b^2=c^2
with that you can solve anything, even if you need to find the value of a leg, just rearrange the equation to help you solve for one of the the legs. and always remember the hypotenuse is the longest side:) hope this helps some

- mm3591

When doing hypotenuse, both legs should add up to the hypotenuse... just a tip
