Find measure.<br> m ∠ 5
jeka57 [31]

Measure of angle 5 i.e. m∠5 = 50°

<h3>What is measurement of an angle ?</h3>

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

<h3>How to  find angle measurement ?</h3>

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Thus, m∠5 = 50°

What is radical 12 (squared )
natima [27]

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol - includes square roots, cube roots and so forth. Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find.

So √12 is in radical form. I think what you are asking for is to reduce the expression to its simplest radical form.

So 12 = 4*3, √12 = √4 * √3.

We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.

This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.

Bogdan [553]

Answer:

Showing-MY-Work:

4 months is 1/3 of a year. (12 months = 1 year)


Since know that they became 20, after 4 years, then we just times 20 by 3.

Because 3 times 4 = 12
