    Please give answer and explanation and or steps if needed please to check my work.

    1) Draw a right triangle whose sides (not the hypotenuse) have lengths of 8 and 15. Angle A is adjacent to the side of 8, and angle B is adjacent to the side with the length of 15. The tan A=?

    2) For the same triangle in question 1 do for the sin A = ?, cos A, and tan B please.

    3) If sin x = 0, then cos x =

    a 0, b +/- 0.5, c +/- 1, d +/- 0.707, e +/- 0.866

    4) If tan x = 1, then x = ?

    a 0, b pi/4, c pi/3, d pi/2, e pi

    5) What is the radius of a circle whose area is A?

    a (pi) * A^2
    b the square root of A divided by pi
    c A divided by 2 * pi
    d the square root of pi divided by A
    e A divided by pi

    6) Where does the graph of the line y=mx +b cross the x axis?

    a b, b m/b, c b/m, d -b/m, e -m/b

    7) There are 15 students for each professor. Let S = the # of students, and P = the number of profs. A correct expression for this is?

    a P=15S,
    b S=15P
    c P/S=15
    d P+S=16
    e S-P=14

    Thank you!
