How is length of chord related to length of a diameter
Andrew [12]
This means that it sweeps out half of the circle so that the chord is actually going across the whole diameter of the circle. So if the chord is going across the diameter and has a length of 15 inches, then the radius of the circle should be 7.5 inches. read more at: https://www.ck12.org/trigonometry/Length-of-a-Chord/lesson/Length-of-a-Chord-TRIG/

Can Anybody Help me?
Leviafan [203]

Answer:

x=8, y=-1

Step-by-step explanation:

The figure is said to be a rectangle, which means opposite sides have to be equal in length. From this, we can write a system of equations:

5x-2y=42

2x+3y=13

There are a number of ways to solve this but I'll go with elimination--that means you need to try to remove one variable first by manipulating the equations and solve for the other variable. Then you use the solution to solve for the variable you initially removed. That sounds confusing, but let me show you how to do it.

If you multiply the first equation by 3 and the second equation by 2, you'll have have:

15x-6y=126

4x+6y=26

Now, we can add these two equations. The y will cancel out, so we can easily solve for x.

19x=152

x=8

Use this value of x to substitute back into either of the original equations to find y.

5(8)-2y=42

40-2y=42

-2y=2

y=-1
