Find the missing side length using the Pythagorean Theorem.<br> a²+6² = c²

r-ruslan [8.4K]

Answer:

Step-by-step explanation:

Hello!

In the Pythagorean theorem, the summation of the square of the legs in a right triangle is equal to the square of the hypotenuse.

Let a and b be the legs, and c is the hypotenuse.

a² + b² = c²

In this equation, the hypotenuse is 30, and the measure of one leg is 24.

We can solve this by plugging in the values.

a² + b² = c²
24² + b² = 30²
576 + b² = 900
324 = b²
b = 18

So the missing side length is 18.

8 blocks because 2/10=1/5 so if they total 4/5 then 2/10+2/10+2/10+2/10=8/10=4/5

What is the slope of the graph?

Dennis_Churaev [7]

Answer:

-4

Step-by-step explanation:

Slope can be found with $\frac{y2-y1}{x2-x1}$

Pick two points on the graph that the line runs through

(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2

Insert the coordinates into the formula

$\frac{0-4}{(-1)-(-2)}$

$\frac{-4}{-1+2}$

$\frac{-4}{1}$

Therefore the slope is -4
