Answer:

Step-by-step explanation:

The three angles of a triangle always have to equal 180 in the end, so if you use the method which is the 4 in this instance, it is an obtuse angle that is equal to the top and left angle. You can add 1 and 2 to get 4, and do 4-3 to get 1+2, So, 4=1+2.

If each exterior angle of a regular polygon measures 15°, how many sides does the polygon have?

Yuri [45]

Answer:

24

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide this by the size of 1 exterior angle to find number of sides, that is

number of sides = $\frac{360}{15}$ = 24

What is the area of a pizza with a diameter of 12 inches? Round to the nearest tenth. Use 3.14 for pi.

Flauer [41]

Answer:

$\boxed {\boxed {\sf a \approx 113.0 \ in^2}}$

Step-by-step explanation:

Assuming this pizza is a circle, we can use this formula for area:

$a= \pi r^2$

1. Find Radius

We are given the diameter: 12 inches, but the formula uses radius.

The radius is half the diameter, or:

$r=\frac{d}{2}$

$r=\frac{12 \ in}{2}$

$r= 6 \ in$

2. Calculate Area

Substitute the radius (6 inches) in for r. The question also asks us to use 3.14 for pi.

$a= (3.14)(6 \ in)^2$

Solve the exponent.

(6 in)²= 6 in* 6 in= 36 in²

$a= (3.14)(36 \ in^2)$

Multiply.

$a= 113.04 \ in^2$

3. Round

The question asks us to round to the nearest tenth.

The 4 in the hundredth place tells us to leave the 0 in the tenth place.

$a \approx 113.0 \ in^2$

The area of the pizza is about 113.0 square inches.

Solve for Z<br> N=5sy^4-7sz

Tcecarenko [31]

Answer:

z = (5sy^4 - N) / 7s

Step-by-step explanation:

N = 5sy^4 - 7sz

Add 7sz to both sides:

N + 7sz = 5sy^4

7sz = 5sy^4 - N

Divide both sides by 7s:

z = (5sy^4 - N) / 7s.
