3x + 4x +5x = 54   (because the perimeter = sum of its dies)

12x = 54

x = 4.5

So the 3 sides are 3*4.5 , 4*4.5 and 5*4.5

= 13.5, 18 and 22.5  units (answer)

Law of reflection. Easy question please help (picture included)
PIT_PIT [208]
<span>Simple. The Law of Reflection states that the angle of incidence is equal to the angle of reflection. These two angles are measured relative the normal line (line perpendicular to the surface). The angle of reflection is therefore 34 degrees also.  However, since the question is asking for the angle relative to the mirror, then the answer is 90-54 = 36</span>° Thus your answer is C. 36°

How do you find the total amount given the percentage of a partial amount
Kay [80]

The whole value can be found by using a phenomenon known as proportion

What is percentage?

A figure or ratio stated as a fraction of 100 is called a percentage. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

Now we are given a percent p of a value let us say x and that value be v

We have to find the initial value let us say that value to be 'P'

To find that we use proportion

That is ratio of value to their respective percentage will be equal

Hence we will have

P/100 = v/ x

P= (v/x)*100

Hence we get the initial value
