Start with the given equation.

P1V1=P2V2

To solve for P2, move anything else on that side to the other side so that P2 is alone.

P1V1=P2V2
P2=P1V1/V2

What is the area of this triangle in square inches?
adelina 88 [10]

The area of a triangle is found by multiplying the base by the height, then dividing that by 2:

Area = 10 * 7 = 70

70 / 2 = 35 square yards.

Ivan

Answer:

In fact, the AB could be calculated in a quickest way, using Pythagorean theorem. In here, we try to use the property of trigonometry to work out AB.

Before applying trigonometry, in this right triangle we can calculate the remaining angle C:

C = 180 - 90 - A = 180 - 90 - 53.13 = 36.87 deg

We can use cosine formula, but here we use the sine formula for the sake of convenience. We have:

sine(angle measure) = ratio of opposite side over hypotenuse

In detail, sineC = AB/BC

Then, we have: AB = BC x sineC = 15 x sin(36.87 deg) = 9.000002 = ~9 ft

Hope this helps!

Someone help i need an answer

Remember that the formula for the perimeter of a rectangle is:

2w + 2l

  • w is the width of the rectangle
  • l is the length of the rectangle

Thus, in this case, you can see that we are adding two of the same monomials and two of another monomial. One monomial is x + 15 and another monomial is x + 5. In this case, these monomials would fulfill the perimeter equation of a rectangle.


Applying this perimeter structure, we can find that this expression represents a perimeter equation of a rectangle with sides x + 15 and x + 5.
