Help, I don’t understand this DeltaMath question
djyliett [7]
I can use the angle and the length of JH to find the length of IJ.

To do this, I look at the relationship IJ and JH have to the 52 degree angle. JH is opposite to angle I, and IJ is adjacent to angle I. Because the two side lengths are opposite and adjacent, I use the tangent function to solve this.

Tangent of an angle = the length of the opposite side / the length of the adjacent side. This is just another way to say tan(x)=opposite/adjacent

Now I can fill in what I know...
tan(52)=4.2/x
Now, I want to isolate x.
tan(52) = 4.2/x
x(tan(52))=4.2
x=4.2/tan(52)

Now I put 4.2/tan(52) into a calculator and get x = 3.3 ft

Hope this helps!

Prove that the value of the expression (125^2+25^2)(5^2–1) is divisible by 3
Radda [10]

Step-by-step explanation:

A =(125^{2} + 25^{2} ) (5^{2} - 1)\\A = [(5^{3})^{2}  + (5^{2})^{2} ] . (5^{2} - 1)\\A = (5^{6}  + 5^{4} ). (5^{2} - 1)\\A = [5^{4} . ( 5^{2}  + 5)].(5^{2} - 1) \\A = 5^{4} . (25+ 5). (5^{2} - 1)\\A = 5^{4} . 30. (5^{2} - 1)\\

Since 30 is divisible by 3

Thus, A is divisible by 3

Good luck!

Solve 20 - x/3 = x/2 , put the number only in the box.
Nikitich [7]

Answer:

<h2>x = 24</h2>

Step-by-step explanation:

20 -  \frac{x}{3}  =  \frac{x}{2}

Multiply through by the LCM that's 6 in order to eliminate the fraction

That's

6 \times 20 - 6 \times  \frac{x}{3}  = 6 \times  \frac{x}{2}  \\ 120 - 2x = 3x

Using the addition property add 2x to both sides of the equation

That's

3x + 2x = 120 + 2x - 2x \\ 5x = 120

<u>Divide both sides by 5</u>

\frac{5x}{5}  =  \frac{120}{5}

We have the final answer as

<h3>x = 24</h3>

Hope this helps you
