If i have all the angles and one side can i find the other sides

1 answer:

6 0

Sure, that's what solving triangles is. Trigonometry has a short menu. Basically we choose between three formulas: Law of Sines, Law of Cosines, Sum of Triangle Angles

The Law of Sines has two sides and two opposite angles; given any three we can solve for the fourth.

The Law of Cosines has three sides and one angle; again given any three we solve for the remaining one.

The Sum of Triangle Angles says all three angles add to 180 degrees, so given two we can find the third.

Here we have all the angles and one side, that's Law of Sines to get the remaining sides.

Which of the following represents the sum of the polynomials below?

zysi [14]

Answer:

Step-by-step explanation:

First, you have to align the like terms next to each other so that it will be easier to combine like terms. (Like terms have the same variables and powers)

$6x^3+(-2x^3)+2x^2+5x^2+9x+3x$

Combine like terms:

(When combining like terms all you have to do is add/subtract the coefficients, number in front of variables, and leave the variable and exponents)

$6x^3+(-2x^3)= > 6x^3-2x^3=4x^3$

$2x^2+5x^2=7x^2$

$9x+3x=12x$

So, we get $4x^3+7x^2+12x$

How much pure acid should be mixed with 6 gallons of a 50% acid solution in order to get a 70% acid solution?

Mashutka [201]

To help with thinking about this, we can say that the 6 gallons of 50% acid contains 3 gallons of pure acid and 3 gallons of filler. This would make the concentration 3/6, or 50%. Adding a gallon of pure acid would shift the concentration to 4/7, or 57.1%.

When the relationship becomes 70%, four gallons of pure acid have been added.

3+4 7
—— = — = 70%
6+4 10
