Answer:
Below in bold.
Explanation:
cos Ф = -24/25
Length of the opposite side of the triangle = √(25^2 - 24^2)
= √49
= 7.
So the hypotenuse is 25, the opposite side = 7 and the adjacent side is 24.
sin Ф = 7/25 ( sine is positive in Quadrant 2),
tan Ф = sin Ф / cos Ф
= 7/25 / -24/25
= -7/24
cot Ф = 1 / tan Ф
= -24/7.
sec Ф = 1 / cos Ф
= -25/24.
csc Ф = 1/ sin Ф
= 25/7.
