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 .

Hypotenuse^{2} =Perpendicular^{2} +Base^{2}

Hypotenuse = Longest Side = 58

58^{2} =40^{2} +42^{2}

3364=1600+1764

3364=3364

Hence proved

So, the given triangle is a right angled triangle .

Help its difrrent question thx so much

Answer:

75% off

Step-by-step explanation:

I would personally say use a calculator, but whatever your instructor says.

First, do $600 off. You could also do 75% off first, but you choose. If you subtract $600 from $868, you get $268.

Next, do 75% off. If you take 100% - 75%, you get 25%, or 1/4. Multiply $868 by 1/4 and you get $217, which is the better deal.

So, to conclude, $217 is less than $268, and therefore 75% off is the better deal.
