$x+2.9-\text{the length of two side}\\x-\text{the length of third side}\\\\\text{The equation}\\\\x+x+2.9+x+2.9=16\\3x+5.8=16\ \ \ \ \ \ |-5.8\\3x=10.2\ \ \ \ |:3\\x=3.4\\x+2.9=6.3\\\\Answer:\ 6.3\ cm,\ 6.3\ cm\ and\ 3.4\ cm$

What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?

inysia [295]

Notice the "x" and "y" coordinates

the x-coordinate is well, the cosine value
the y-coordinate is well, the sine value

now the tangent

$\bf tan(\theta)=\cfrac{opposite}{adjacent}=\cfrac{y}{x}\\\\
-------------------------------\\\\
tan(\theta )=\cfrac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}}\implies tan(\theta )=-1$
