MCQ

If $\alpha+\beta+\text{y}=2\text{p},$ then:

✓
$\frac{\tan\alpha}{2}+\frac{\tan\beta}{2}+\frac{\tan\text{y}}{2}=\frac{\tan\alpha}{2}.\frac{\tan\beta}{2}.\frac{\tan{\text{y}}}{2}$
B
$\frac{\tan\alpha}{2}.\frac{\tan{\beta}}{2}+\frac{\tan{\beta}}{2}.\frac{\tan{\text{y}}}{2}=\frac{\tan\text{y}}{2}.\frac{\tan{\alpha}}2=1{}$
C
$\frac{\tan\alpha}{2}+\frac{\tan\beta}{2}+\frac{\tan\text{y}}{2}=\frac{\tan\alpha}{2}.\frac{\tan\beta}{2}.\frac{\tan\text{y}}{2}$
D
$\text{None of these}$

✓

Answer

Correct option: A.

$\frac{\tan\alpha}{2}+\frac{\tan\beta}{2}+\frac{\tan\text{y}}{2}=\frac{\tan\alpha}{2}.\frac{\tan\beta}{2}.\frac{\tan{\text{y}}}{2}$

$\frac{\tan\alpha}{2}+\frac{\tan\beta}{2}+\frac{\tan\text{y}}{2}=\frac{\tan\alpha}{2}.\frac{\tan\beta}{2}.\frac{\tan{\text{y}}}{2}$
