TRIGONOMETRY (sin, cos, tan)

Solve for x

22.6

Step-by-step explanation:

The cos of any angle is its adjacent over its hypotenuse:

cos 37 = 17.3 / x

We can multiple both sides by x to get x * cos 37 = 17.3 and then we can divide both sides by cos 37 to get x by itself:

x = 17.3 / cos 37

So solving for x, x is equal to about 22.6

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
