The sum of the interior angles of a polygon can be found using this formula : sum = 180(n - 2)....where n is the number of sides ur polygon has. Ur polygon has 5 sides....so the sum of ur angles are : 180(5 - 2) = 180 * 3 = 540. So ur angles have to add up to 540.

90 + 107 + 144 + 138 + x = 540
479 + x = 540
x = 540 - 479
x = 61 <===

A shelf is built on a wall, as shown below. What is the value of x?<br> (2x+1) + (3x-1)

Hoochie [10]

Answer:

x = 18

Step-by-step explanation:

We need to find the value of x.

We know that the sum of angles of a triangle is equal to 180°. So, using this property,

2x+1+3x-1+90 = 180

2x+3x = 180-90

5x = 90

x = 18

So, the value of x is equal to 18.

The distance from the center of a carousel to the

anzhelika [568]

Answer:

$\fbox{\begin{minipage}{3.5em}338 (ft)\end{minipage}}$

Step-by-step explanation:

The problem could be simplified as following:

Given:

The radius of a circle O is 26 feet.

Solve for:

The length of arc on circle O that measures 13 radians

Solution:

Step 1: Let's find out the correct formula to apply:

The formula to calculate the length of an arc measuring x radians on a circle with radius r feet is:

L = r*x

Step 2: Let's put the data into formula to work out the length L of arc:

L = 26*13 = 338 (ft)

=> The distance that a horse does on the outer edge travel when the carousel rotates through 13 radians: L = 338 (ft)

Hope this helps!
