So i'm in an online class of geometry and one of the units is trig. but no matter how long i keep learning or trying to learn the notes and lesson i cant figure what it means. or how to solve the triangle with anything other than pythagorean's theorem which doesn't solve it or even . and i try to look for a simpiler way to look at it but i cant find one.

Answer and explanation:

There are six main trigonometric ratios, namely: sine, cosine, tangent, cosecant, secant, cotangent.

Those ratios relate two sides of a right triangle and one angle.

Assume the following features and measures of a right triangle ABC

Then, the trigonometric ratios are:

Then, if you know one angle (other than the right one) of a right triangle, and any of the sides you can determine any of the other sides.

For instance, assume an angle to be 30º, and the lenght of the hypotenuse to measure 5 units.

Thus, you have solved for the two unknown sides of the triangle. The three sides are 2.5, 4.3, and 5.

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
