1) Use sine ratio

sin (45°) = adjacent leg / hypotenuse

=> adjacent leg = hypotenuse * sin(45°)

adjacent leg = 24 * (√2/2) = 12√2

Given that the triangle is isosceles the two legs have the same length.

Answer: 12√2

A 45-45 90 triangle has two lengths that are equal, and the hypotenuse is √2 times those lengths.

Therefore:
Let x = the length of a leg (doesn't matter which one, they are equal)
√2 * x = 24 Divide both sides by √2
x = 24 / √2
To get the radical out of the denominator, multiply the right side by √2/√2
x = 24√2 / 2
x = 12√2 Answer is B

What is a circumference of a smaller circle the raduis of a smaller circle 3inch and the the raduis of a larger is circle is 7so

Art [367]

Answer:

18.85 inches.

Step-by-step explanation:

We have been given that the radius of a smaller circle 3 inch. We are asked to find the circumference of smaller circle.

We know that circumference of a circle is equal to $2\pi r$ , where r represents radius of circle.

$\text{Circumference of smaller circle}=2\pi (3\text{ inches})$

$\text{Circumference of smaller circle}=6\pi\text{ inches}$

$\text{Circumference of smaller circle}=18.84955592\text{ inches}$

$\text{Circumference of smaller circle}\approx 18.85\text{ inches}$

Therefore, the circumference of smaller circle is approximately 18.85 inches.

The length of a rectangle is five times it’s width if the area of the rectangle is 320m^2 find its perimeter

BlackZzzverrR [31]

Answer:

Perimeter of the rectangle = 96 meters.

Step-by-step explanation:

Let the width of the rectangle = K

So, the length of the rectangle = 5K

Area = 320 sq meters

Now, Area of a Rectangle = Length x Width

⇒ 320 = K x 5K

or, $5K^{2} = 320\\or, K^{2} = \frac{320}{5} = 64$

So, the vlue of K = 8 or, K = -8

But as K represents a length hence, K ≠ -8

So, the <u>width of the rectangle = 8 meters</u>

and the<u> length of the rectangle = 8 x 5 = 40 meters</u>

Now, Perimeter = 2(length + width)

= 2(8 + 40) = 96 meters.

So, the perimeter of the rectangle = 96 meters.
