Question

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!

A triangle has sides with lengths of 50 millimeters, 65 millimeters, and 83 millimeters. Is it a right triangle?

Yes or no?

Answer 1

No

Explanation:

we know that

The length sides of a right triangle must satisfy the Pythagorean Theorem

so

`c^2=a^2+b^2`

where

c is the hypotenuse (the greater side)

a and b are the legs (perpendicular sides)

we have

`c=83\ mm\\a=50\ mm\\b=65\ mm`

substitute the given values

`83^2=50^2+65^2`

`6,889=2,500+4,225`

`6,889 \\eq 6,725`

therefore

Is not a right triangle
