Question

Use the triangle to evaluate each function. sin(A) = tan(A) = sec(A) =

Answer 1

sin(A) = 3/5

tan(A) = 3/4

sec(A) =5/4

Which of the following is equal to tan(A)?

cot(B)

Answer 2

`\sin\alpha=(opposite)/(hypotenuse)\\\\\cos\alpha=(adjacent)/(hypotenuse)\\\\\tan\alpha=(opposite)/(adjacent)\\\\\sec\alpha=(1)/(\cos\alpha)=(hypotenuse)/(adjacent)\\\\\text{We have:}\\opposite=3\\adjacent=4\\hypotenuse=5\\\\\text{subtitute:}\\\\\sin(A)=(3)/(5)\\\\\tan(A)=(3)/(4)\\\\\sec(A)=(5)/(4)`
