(120°<br> 3x<br> 2x<br> Solve for x!<br> 120<br> 24<br> 360<br> 20
Alexandra [31]

Answer:

The angles in a triangle should always add up to 180 degrees.

The four angles made by a set of intersecting lines will always add up to 360 degrees and the ones across from eachother are always the same.

This means that the triangle's unmarked angle is 60 degrees.

2*24 = 48 and 3*24 = 72       48 + 72 + 60 = 180 degrees

24 will be your correct answer.

Find the two-digit number which is 2 times the sum of its digits. Find a statement and number, please.
poizon [28]
A two-digit number is twice the sum of its digit. If the tens digit is 7 less than the unit digit, find the number. 
Let x= the unit digit
Then y= the tens digit
<span>And 10y+x= the number 


</span>x+y= the sum of the digits 
<span>Now we are told that 10y+x=2(x+y) ------1st equation </span>
<span>We are also told that y=x-7 ----------- 2nd Equation </span>
<span>So our equations to solve are: </span>
(1) 10y+x=2(x+y)
<span>(2) y=x-7 
</span>

Hope it helps

22. The area of a triangle can be represented by the expression 14x^5 + 63x^2. If the base is 7x^2, write
kkurt [141]

Answer:

h = 4x ^ 3 + 18

Step-by-step explanation:

The first thing you should know for this case is that the area of a triangle is given by:

A = (1/2) * (b) * (h)

Where,

b: base.

h: height.

Clearing the height we have:

h = ((2) * (A)) / (b)

Substituting the values

h = ((2) * (14x ^ 5 + 63x ^ 2)) / (7x ^ 2)

Simplifying the expression:

h = ((2) * (2x ^ 3 + 9))

h = 4x ^ 3 + 18

answer

an expression to represent its height is

h = 4x ^ 3 + 18

Do anyone know the answer to this? Answers please?
Amanda [17]

Answer:

Yes

Step-by-step explanation:

You can check whether the ratios form a proportion, by setting one piece of the ratios as x

Thus, we can use the equation 4/3.2=22/x.

From this, we get 4x=70.4.

Solving for x gives us 17.6.
