Respuesta :
Simple Pythagorean theorem, And if you double check Tamara's work she is correct. Therefor B is the correct answer.
Answer:
The given triangle is a right angled triangle .
Step-by-step explanation:
Given : Side Lengths of Triangle are 40,42 and 58
To Find: To determine if a triangle with side lengths of 40, 42, and 58 is a right triangle.
Solution:
To check whether the given triangle is a right angled triangle or not we will use Pythagorean theorem .
[tex]Hypotenuse^{2} =Perpendicular^{2} +Base^{2}[/tex]
Hypotenuse = Longest Side = 58
[tex]58^{2} =40^{2} +42^{2}[/tex]
[tex]3364=1600+1764[/tex]
[tex]3364=3364[/tex]
Hence proved
So, the given triangle is a right angled triangle .
