Answer:

length of other leg = 20'

Step-by-step explanation:

Given:

One leg of triangle let it be base of triangle = 21'

Hypotenuse = 29'

To Find:

Third leg =perpendicular = ?

Solution:

Given is a right angled triangle with two of its sides given to us

We have Pythagoras theorem for right angled triangle and according to it

Pythagoras theorem is

for a right angled triangle

(hyp) ² = (perp)²+(base)²

We have the values of hyp and base

putting them in the equation we get

(29) ² = (perp) ²+(21) ²

841 = (perp) ² + 441

subtracting 441 from both sides we get

841 - 441 = (perp) ² + 441 - 441

400 =  (perp)²

or

(perp) ²=400

Taking square root of both sides

\sqrt{(perp)^{2} }=\sqrt{400}

it gives us

perp = ± 20'

As it is length and it can not be negative so

perp = 20'

or

length of other leg = 20'

The area of a rectangle is 46 square inches. If the length is 4 times the width, then find the dimensions of the rectangle. Roun
vampirchik [111]

The dimensions of the rectangles to the nearest hundredth are

  • length = 13.56 inches
  • width = 3.39 inches

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

A rectangle is four sided plane figure which each pair of sides equal and opposite to each other. The sides intersect at an angle of 90 degrees.

<u>Given data</u>

Area of the rectangle = 46 square inches

length L = 4 * width W

area of a rectangle, A

A = L * W

46 = L * W

46 = 4w * w

46 = 4w^2

w^2 = 11.5

w = sqrt ( 11.5 )

w = 3.391 inches

w = 3.39 to the nearest hundredth

since L = 4w

L = 4 * 3.391

L = 13.564

L = 13.56 to the nearest hundredth

Sedbober [7]

Answer:

The answer is 1 over 5
