Question

Using the information given in fig. write the values of all trigonometric ratios of angle C.

Answer 1

Using the defination of t-ratios

sin C = $\frac{AB}{AC}=\frac{8}{10}=\frac{4}{5}$ ; cos C = $\frac{BC}{AC}=\frac{6}{10}=\frac{3}{5}$

tan C = $\frac{AB}{BC}=\frac{8}{6}=\frac{4}{3}$ ; cot C = $\frac{BC}{AB}=\frac{6}{8}=\frac{3}{4}$

sec C = $\frac{AC}{BC}=\frac{10}{6}=\frac{5}{3}$ and cosec C = $\frac{AC}{AB}=\frac{10}{8}=\frac{5}{4}$
