Step-by-step explanation:
5n - 2 => 2 less than 5 times a number
2(5 + n)=> Twice the sum of 5 and a number
2n + 5 => The sum of twice a number and 5
5n/2 => Half of <u>5</u> times a number:
2 - 5n => The product of 5 and a number less than 2
First, tan(<em>θ</em>) = sin(<em>θ</em>) / cos(<em>θ</em>), so if cos(<em>θ</em>) = 3/5 > 0 and tan(<em>θ</em>) < 0, then it follows that sin(<em>θ</em>) < 0.
Recall the Pythagorean identity:
sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1
Then
sin(<em>θ</em>) = -√(1 - cos²(<em>θ</em>)) = -4/5
and so
tan(<em>θ</em>) = (-4/5) / (3/5) = -4/3
The remaining trig ratios are just reciprocals of the ones found already:
sec(<em>θ</em>) = 1/cos(<em>θ</em>) = 5/3
csc(<em>θ</em>) = 1/sin(<em>θ</em>) = -5/4
cot(<em>θ</em>) = 1/tan(<em>θ</em>) = -3/4
Answer:
Step-by-step explanation:
Divide both sides by 9 to isolate x:
Hope this helps!
8 x 2 = 16
Square root of 16 = 4
One side of the square is 4 meters.
