Sarvesh K Verma Solutions for Chapter: Trigonometry, Exercise 5: Introductory Exercise

Find $\mathrm{B}$ and $\mathrm{C}$ of a triangle $\mathrm{ABC}$, if $\mathrm{b}=2 \mathrm{cm},\mathrm{c}=1 \mathrm{cm}$ and $\mathrm{A}=60°$ :

In a triangle $\mathrm{ABC},\mathrm{a}=1 \mathrm{cm},\mathrm{b}=\sqrt{3} \mathrm{cm}$ and $\mathrm{C}=\frac{\mathrm{\pi }}{6}$ , find the third side of the triangle:

If $\mathrm{a}=2 \mathrm{b}$ and$\mathrm{A}=3 \mathrm{B}$, find the $\mathrm{A}, \mathrm{B}, \mathrm{C}$angles of $∆\mathrm{ABC}$.

In a right angled triangle  ${\mathrm{a}}^2+{\mathrm{b}}^2+{\mathrm{c}}^2$ is :

Abhinav and Brijesh started walking simultaneously @ $3 \mathrm{km}/\mathrm{h}$ and $4 \mathrm{km}/\mathrm{h}$from the same point '$\mathrm{C}$ ' on two different paths which diverge from each other at an angle of $120°$. They walked for 6 hours and they stopped at $\mathrm{A}$ and $\mathrm{B}$ respectively. What is the least possible distance between Abhinav and Brijesh when they are at$\mathrm{A}$ and $\mathrm{B}$respectively.
