To convert hour into minute: (No. of hour × 60) minutes

So, 2/5 hours = (2/5 × 60) minutes = (120/5) minutes = 24 minutes

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,

M=multiplication

A=addition

S=subtraction

so when you are opening a bracket you multipli the number in the bracket with the one outside the bracket
