Question

1. find the value of sin theta and tan theta
2. write an expression for AD in terms of theta

Answer 1

hello friend,

AB = 14

BC= 12

AC =?

By using Pythagoras theorem

(AC)^2= (AB)^2 + (BC)^2

(AC)^2= (14)^2 + (12)^2

( AC)^2= 196+144

AC ^2=340

AC =
$\sqrt{340}$
Sin theta=
$\frac{1}{? \sqrt{340} }$

tan theta = 12/14
