Question

2
a) In a right triangle ABC, right-angled at B ,if tan a
= 1, then verify that 2 sin Acos A =1​

Answer 1

Step-by-step explanation:

$\tan(a) = 1 \\ \tan(a) = \tan(45) \\ a = 45 \\ \\ = > 2 \sin(a) \cos(a) \\ \\ = > 2 \sin(45) \cos(45) \\ \\ = > 2 \times \frac{1}{ \sqrt{2} } \times \frac{1}{ \sqrt{2} } \\ \\ = > 2 \times \frac{1}{2} = 1$
