and since we know now what "x", let's use that in either equation, say the first equation,
another way to do it is by "elimination", depending on the equations, one way may work quicker than the other, in this case, substitution was the simpler one, because the first equation is already solved for "y", so we just grabbed it and plugged it in the 2nd equation.
Your answer will be B. Just message me if you have a question on how it's that answer
Answer:
In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.
