Question

If tanA=0.75,what will be the ratios of other trignometrical ratios.

Answer 1

Answer: Sin A = $\frac{3}{5}$

              Cos A = $\frac{4}{5}$

              Cosec A =  $\frac{5}{3}$

              Sec A =  $\frac{5}{4}$

             Cot A =  $\frac{4}{3}$

Step-by-step explanation:

tan A = 0.75

         = $\frac{3}{4}$ = $\frac{p}{b}$

Consider a right angled triangle with side 3,4,5 with the angle A in front of pependicular(p) of length 3.

i.e p =3

   b =4

   h= 5

Sin A = $\frac{p}{h}$

Cos A = $\frac{b}{h}$

Cosec A = $\frac{1}{Sin A}$

Sec A =$\frac{1}{Cos A}$

Cot A = $\frac{1}{Tan A}$
