Based on the trigonometric calculations, the value of cosC is equal to: C. 15/17.
The types of trigonometry graph.
In Mathematics, there are six (6) types of trigonometry graph that are used to graphically represent a trigonometric function and these include:
Based on the right-angled triangle attached, we can deduce the following parameters:
Opposite side (BA) = 8 units.
Adjacent side (BC) = 15 units.
Hypotenuse (AC) = 17 units.
In trigonometry, cosine (cos) is given by this mathematical expression:
cosC = BC/AC
cosC = 15/17.
