Question

In a right angle triangle ABC with right angle at B, in which a = 24 units, b = 25 units and angle BAC = theta. then, find cos theta and tan theta

Answer 1

As Right ∆ABC, with Right Angle at B...
A
|\
| \
|. \
B. C

AB=24 ut. BC=25ut

Angle BAC=∅
:- by Pythagoras Theorem:
p²+b²=h²
24²+25²=h²
then solve it and you will get the value of h or AC.
After that find cos∅=b/h or BC/AC
and tan∅=p/b or AB/BC
