Question

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?

Answer 1

please help

Answer 2

The length of the hypotenuse of a right triangle is 24 inches. If the length of one leg is 8 inches, what is the approximate length of the other leg?

Answer 3

thats another question

Answer 4

:(

Answer 5

its 22.6 for the second question

Answer 6

Answer 13

yesssh i do

Answer 14

What is the length of the unknown side of the right triangle?

A right triangle with hypotenuse x and legs 21 and 20

21
29
400
441

Answer 15

(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

Answer 16

thx man

Question 1 (Multiple Choice Worth 1 points)

(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.

Answer 23

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?
