Answer: x = 40.81 or 41

Step-by-step explanation:

A = B = 21

C = 35

Hypotenuse = x

Calculating Hypotenuse:

21^2 + 35^2 = x^2

=> 441 + 1225 = x^2

=> x^2 = 1666

=> x = 40.81 or 41

Use the slope formula to find the slope of the line going through points (–2, 3) and (4, 0).
chubhunter [2.5K]

Answer:

The answer is

\huge  -  \frac{1}{2}  \\

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

From the question we have

m =  \frac{0 - 3}{4 -  - 2}  =  \frac{ - 3}{6}  =  -  \frac{1}{2} \\

We have the final answer as

-  \frac{1}{2}  \\

Hope this helps you
