Answer:

Step-by-step explanation:

Recall that cos Ф = adj / hyp.  If adj = 6 and hyp = 10, then by the Pythagorean Theorem, opp = 8:    6² + 8² = 10²

Then:

sin Ф = opp / hyp = 8/10 or 4/5

cos Ф is given:         6/10 or 3/5

tan Ф = opp / adj:      8/ 6 or 4/3

cot Ф   = 1/sin Ф = 10/8 or 5/4

sec Ф  = 1/ cosФ  =  10/6 or 5/3

csc Ф  = 1 / sin Ф = 10/8 or 5/4
