Question

In each of the following, one of three trigonometry ratios is given. find the other two ratios : Tan A=3 solution

Answer 1

Answer:

Sin A=3/root10

Cos A=1 /root 10

Step-by-step explanation:

Tan A=P/B

=P/B=3/1

By the pathagoras theorem, we get

AC

${ac}^{2} = {ab}^{2} + {bc}^{2}$

We get root 10.

Sin A=p/h=3/root 10

Cos A=b/h=1/root 10
