Answer:
tan= -4/3
[tex]tan^-1(-4/3)\\=53.13\\[/tex]
-4 is the opposite
-3 is the adjacent
[tex]sin(-53.1301)*sin(-53.1301)\\\frac{4}{5} *\frac{4}{5}\\\frac{16}{25}=0.64[/tex]
Step-by-step explanation:
We will find the angle
We will then use the angle to find the sin value and multiply them both to find the square.
I will suggest you keep to fractions will working.
