Use the Pythagorean theorem to find the lengths of the sides of the right triangle. Use a calculator when necessary. A right tri
Doss [256]

Answer:

The length of the sides of the right angle triangle

15 , 25, 20

Step-by-step explanation:

<u>Explanation</u>:-

<u>Step(i):-</u>

we know that by using Pythagorean theorem to find the lengths of the sides of the triangle

AC² = AB² + BC²

Given a  right triangle has legs labeled 3m and 2m+10

let us assume that AB = 3m and BC = 2m + 10

Given a hypotenuse  labeled 5m

let us assume that hypotenuse AC = 5m

<u>Step(ii)</u>:-

Now by using Pythagorean theorem

AC² = AB² + BC²

(5m)² = (3m)² + (2m+10)²

25m² = 9m² + 4m² + 40m + (10)²  ( since (a + b)² = a²+2ab+b²) )

on simplification , we get

25m²-13m² -40m -100 =0

12m² -40m -100 =0

4(3m² -10m -25) =0

3m² -10m -25 =0

3m² - 15m + 5m -25 =0

3m(m-5) + 5(m-5) =0

(3m +5) (m-5) =0

3m +5 =0 and m-5=0

3m = -5 and m =5

m = \frac{-3}{5} and m=5

we can not choose negative value

so the value m=5

<u>Step (iii)</u>:-

The sides of right angle triangle

AB = 3m

AB = 3(5) = 15 and

BC = 2m + 10

BC = 2(5) +10 = 20

The hypotenuse AC =  5m

                           AC = 25

<u>Conclusion:</u>-

The  lengths of the sides of the right triangle

15, 25 ,20

Kellie has 3/5 hour left to finish 6 math problems on the test how much time does she have to spend on each problem
seropon [69]

Answer:

6 minutes

Step-by-step explanation:

There are 60 minutes in an hour. This can be broken up into 5 12-minute intervals. From there, you can do 3 intervals of 12 minutes which is 36 minutes. The 36 minutes is divisible by 6 questions getting to 6 minutes per question.

Which of the following is a degenerate circle?
LekaFEV [45]

The require degenerative circle is (x - 5)² + (y - 1)² = 0. Option C is correct.

Given that,  
The equation for the degenerative circle is to be determined.

<h3>What is a circle?</h3>

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.

The degenerative circle is a circle whose radius is zero, from the option,
Option C has the equation of the circle with radius zero.

Thus, the required degenerative circle is (x - 5)² + (y - 1)² = 0.

The radius of a sphere is 6 inches. Find the length of a chord connecting two perpendicular radii. x = inches
Lilit [14]
<h3>Answer:</h3>

6√2 ≈ 8.485 inches

<h3>Step-by-step explanation:</h3>

The radii and the chord together make an isosceles right triangle with legs 6 inches long. The hypotenuse of such a triangle is √2 times the leg length. So, the chord will be 6√2 in long.

_____

<em>Comment on isosceles right triangle</em>

It is worth remembering that the hypotenuse of an isosceles right triangle is √2 times the leg length. This is easily found using the Pythagorean theorem:

... c² = a² + b²

... c² = 1² + 1² = 2 . . . . for legs of length 1

... c = √2 . . . . . . . . . . take the square root.

Scale this result as needed for any particular problem. Here, the scale factor is 6 inches.
