<PRE><B>Question 1041412</B>
Using the Pythagorean Theorem we have
:
opposite side^2 = 7^2 - 4^2 = 33
opposite side = square root(33)
:
***************************************************************************
Sec (theta) = 1 / cos (theta) = 1 / (4/7) = 7/4
Sin (theta) = square root (33) / 7
Tan (theta) = sin (theta) / cos (theta) = (square root (33) / 7) / (4/7) = square root (33) / 4
