Answer:

Arc length = 10 pi.

Step-by-step explanation:

Given : Circle W has a radius of 20 in and right central angle.

To find :Find the length of arc in term of pi.

Solution : We have given that Radius of circle = 20 in .

Central angle = 90

Arc length = 2 *pi* r ( $\frac{central\ angle}{360}$ .

= 2 * pi * 20 ( $\frac{90}{360}$ .

Arc length = 40* 0.25 pi

Arc length = 10 pi.

Therefor, Arc length = 10 pi.

Answer:

18 and 11/16

Step-by-step explanation:

I converted the two numbers into improper fractions which leaves me with

71/8+157/16

I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:

142/16+157/16

I can now add the 2 numbers together and I get:

299/16

now we just need to convert the number into a mixed number by dividing, and I am left with:

18 and 11/16

This system has one solution.

mr_godi [17]

Answer: It is 2.

Step-by-step explanation:

Make both equation equal to each other and solve for x, as following:

- Add like terms.

- Factor the equation.

$8x-14=x^{2}+4x-10\\x^{2}+4x-10-8x+14=0\\x^2-4x+4=0\\(x-2)(x-2)=0\\(x-2)^2=0\\x=2$

Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.

Then, this is:

$y=8(2)-14\\y=16-14\\y=2$

35° is the degree of that angle.

All triangles are supposed to be 180° with all the angles put together.

35° plus 90° and 55°

= the angles of that triangle.
