What is the length of the hypotenuse of the triangle ?

10√2 units

Step-by-step explanation:

Given : A right angles triangle QRS

           QS= SR = 10 units

To Find : Hypotenuse

Solution:

Perpendicular = 10 units

Base = 10 units

Hypotenuse = QR

Now we will use Pythagoras theorem

Hence the length of the hypotenuse of the triangle is 10√2 units

So, Option D is correct.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
