Question

In a right triangle ABC , right - angled at B. if tan A=1 , the verify that 2 sina cos A=1.​

Answer 1

Step-by-step explanation:

since you mentioned right angled at B therefore B= 90

and also mentioned tan A = 1 therfore A = 45

substituting angle A

$2 \times \sin(45) \times \cos(45)$

$2 \times \frac{1}{ \sqrt{2} } \times \frac{1}{ \sqrt{2} }$

$\frac{2}{2}$

$1$

Answer 2

Answer:

since you mentioned right angled at B therefore B= 90

and also mentioned tan A = 1 therfore A = 45

substituting angle A
