Answer:
<em>x=25</em>
Step-by-step explanation:
<u>Equilateral Triangle</u>
Equilateral triangles are identified because they have all three sides of the same length and all three angles of the same measure.
The image shows a triangle with its three angles as congruent, thus it is an equilateral triangle.
Since we have two conditions and only one variable, we must be sure both conditions produce the same answer for x.
Equating two of the side lengths:
4x - 30 = 2x + 20
Subtracting 2x, and adding 30:
4x - 2x = 30 + 20
Operating:
2x = 50
x = 25.
Substituting x=25 in all the side lengths:
4x - 30 = 4*25 - 30 = 70
2x + 20 = 2*25 + 20 = 70
3x - 5 = 3*75 - 5 = 70
Once verified, it's sure that x=25

The height of the cone is h = 27
Formula:-
Step 1:-
The volume of the cone is V=\frac{1}{3} (base)(height)V=31(base)(height)
Given volume is V= 45 in^ 3
Given base of the cone is B= 5 in^2
Step 2:-
by using formula, we get solution
45 = \frac{1}{3} (5)(h)45=31(5)(h)
cross multiplication, we get
\frac{45 x 3}{5} =h545x3=h
<em>now simplification, the height of the cone is h = 27</em>

D=rtthe distances are not equal, but they add up to a total of 400 milesone bus goes 55mph times t so that is 55t (that represents the distance in one direction)the other bus goes 45 mph,so that is 45t (that represents the distance in the other direction)the total distance is 400, so the equation is distance one direction + distance the other direction = 400your equation is 55t + 45t = 400 100t = 400 t= 4 hoursso after 4 hours they will be 400 miles apart
