Question

In right triangle ABC, right-angled at B, if tanA=1, then verify that 2sinAcosA=1.​

Answer 1

Answer:

hope this will help you with your problem

Answer 2

Step-by-step explanation:

Given;

TanA =1

To verify : 2sinAcosA=1.

We know, Tan 45 = 1;

Thus, Tan A = Tan 45

 ∠A = 45°

Verifing;

2sinAcosA=1

2 (1/√2)(1/√2) = 1;

2 (1/2) = 1

1 = 1.

Thus, verified.

That's all
