Question

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

Answer 1

Step-by-step explanation:

Given,

tanA = 1

=> tanA = tan45°

=> A = 45°

Now,

$2sinAcosA \\ </p><p>= 2sin45°cos45° \\ = 2 \times \frac{1}{ \sqrt{2} } \times \frac{1}{ \sqrt{2} } \\ = 2 \times \frac{1}{2} \\ = 1</p><p>$

Hence, Verified.
