Answer:

We call the denominator rational.

Step-by-step explanation:

For example:

$\frac{1}{\sqrt{2}} = \frac{\sqrt2}{\sqrt2 \cdot \sqrt2} = \frac{\sqrt2}{2}$

It's clear that the denominator is now a rational number, not an irrational one anymore.

Find the value of x and y

allsm [11]

We have the equations:

x + 3 = 15 and 3y - 1 = 2x - 4

x + 3 = 15 |-3

x = 12

Put the value of x to the second equation:

3y - 1 = 2(12) - 4

3y - 1 = 24 - 4

3y - 1 = 20 |+1

3y = 21 |:3

y = 7

<h3>Answer: x = 12 and y = 7.</h3>

Answer:

First option.

Step-by-step explanation:

In this case you need to remember that an angle formed by two intersecting chords is equal to the sum of the intercepted arcs divided by 2. This is:

$Angle\ formed\ by\ two\ intersecting\ chords=\frac{1}{2}(Sum\ of\ intercepted\ arcs)$

You can identify in the figure that the angle ∠1 is an angle formed by two intersecting chords. Therefore, since the intercepted arcs are SP and QR, you can say the following:

$m\angle 1=\frac{1}2}(mSP+mQR)$

You can observe that this matches with the first option.
