Question

What is sin30? What is cos30? What is tan60?

Answer 1

Answers:

`\sin(30^(\circ)) = (1)/(2)\\\\\\\cos(30^(\circ)) = (√(3))/(2)\\\\\\\tan(60^(\circ)) = √(3)\\\\`

=======================================================

Work Shown:

Problem 1

`\sin(\text{angle}) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin(30^(\circ)) = (7)/(14)\\\\\sin(30^(\circ)) = (1)/(2)\\\\`

-------------------------

Problem 2

`\cos(\text{angle}) = \frac{\text{adjacent}}{\text{hypotenuse}}\\\\\cos(30^(\circ)) = (7√(3))/(14)\\\\\cos(30^(\circ)) = (√(3))/(2)\\\\`

------------------------

Problem 3

`\tan(\text{angle}) = \frac{\text{opposite}}{\text{adjacent}}\\\\\tan(60^(\circ)) = (7√(3))/(7)\\\\\tan(60^(\circ)) = √(3)\\\\`
