Answer:
sum of interior angles - 540
x = 112
Step-by-step explanation:
Hello There!
<u>Geometry</u>
The sum of the interior angles can be found using this formula
let x = sum of interior angles and n = number of sides
x = ( n - 2 ) * 180
there are 5 sides so we plug in 5 to n
5 - 2 = 3
3 * 180 = 540 so the sum of the interior angles is 540
Now to solve for x
Remember the sum of the interior angles is 540 so we use this equation to solve for x
<u>Simple Algebra</u>
540 = x + 118 + 105 + 75 + 130
step 1 combine like terms
118 + 105 + 75 + 130 = 428
now we have 540 = 428 + x
step 2 subtract 428 from each side
540 - 428 = 112
we're left with x = 112
Answer:

Step-by-step explanation:
Given
--- radius
--- distance between chord and the center of the circle
Required
The chord length
See attachment for illustration
First, calculate distance AX using Pythagoras theorem.
This gives:
Collect like terms
Take square roots of both sides
AB is then calculated as:
Where:
So:
