Answer:

Step-by-step explanation:

When subtracting a negative number, you will add it.

This is because the negative signs of the subtraction sign and the negative number will cancel out.

This will change the subtraction sign to a positive sign and will switch the negative sign on the number to a positive one.

So, 3 - (-2) will change to 3 + (2)

3 + 2

= 5

Answer:

99.96

Step-by-step explanation:

Your height is correct.

Part B is asking for the length of the hypotenuse.

76.6^2 + 64.25^2 = x^2

x^2 = 9995.6225

x = 99.96 or 99.98 depending on if you round to 76.6 or not

In a circle of radius 10 cm, a sector has an area of 40 (pi) sq. cm. What is the degree measure of the arc of the sector?

Rashid [163]

Answer:

144°

Step-by-step explanation:

First, find the area of the circle, with the formula A = $\pi$ r²

Plug in 10 as the radius, and solve

A = $\pi$ r²

A = $\pi$ (10²)

A = 100 $\pi$

Using this, create a proportion that relates the area of the sector to the degree measure of the arc.

Let x represent the degree measure of the arc of the sector:

$\frac{40\pi }{100\pi }$ = $\frac{x}{360}$

Cross multiply and solve for x:

100 $\pi$ x = 14400 $\pi$

x = 144

So, the degree measure of the sector arc is 144°
