Answer:

21.5

Step-by-step explanation:

x is the radius of the circle.

If we draw a line from the circle's center to either end of the horizontal line, that line will also be a radius, so it will have length x. This forms a right triangle with side lengths 10 and 19 and hypotenuse x.

Using Pythagorean Theorem:

c² = a² + b²

x² = 10² + 19²

x² = 461

x ≈ 21.5

joy added 26 new contacts to her phone list. She now has a total of 100 contacts. Let c represent how many contacts joy had on h

Nesterboy [21]

Answer: 26 + c = 100

Step-by-step explanation: To find what c equals, we must flip the solution around and subtract it. When we take 100 - 26, we get 74. Therefore, c = 74. I hope this helped! :)

Need help with this math problem

-BARSIC- [3]

z = 37°

Step-by-step explanation:

The exterior angle theorem says that the sum of two internal angles is equal to the exterior angle

In this case the sum of z and z+4 will be equal to z+41

Writing mathematically

$z + z+ 4 = z + 41\\2z+4 = z + 41\\2z -z = 41 -4\\z = 37$

Hence

z = 37°
