If sin(t) = 3/5 and t is in the 2nd quadrant, find cos(t).

NemiM [27]

Cosine is $\frac{hypotenuse}{adjacent}$ .

Apply the equation:

$sin(t) = \frac{3}{5} \\3^2 + b^2 = 5^2\\b^2 = 5^2 - 3^2\\\\\sqrt{b^2} = \sqrt{5^2}- \sqrt{3^2}\\\\\\b = 5 - 3 \\\\b = 2$

B is the adjacent side so

cosine is:

Cos(t) = 5/2

Have a great day,

Answer:

So in other words, each week he works, he gets an additional $10, to add to his collection of really $75.

Step-by-step explanation:

so, he has $85 in savings, and that he has the opportunity to gain allowance by the following function of 10(x-1).

total funds(x) = 85 + 10(x-1)

T(x) = 85 + 10x - 10

T(x) = 10x + 75
