Question

In a right triangle ∆ABC , right-angled at
B if tanA =1, then verify that

2sinA cosA=1 ​

Answer 1

Answer :

"In a right triangle ABC, right-angled at B,

Tan A = 1

Verify that 2 sin A cos A = 1

A=45

2 sin A cos A= 2 sin 45 cos 45 = 2x1/2 = 1

Third side are (AB+BC)≥AC , So Sin C + Cos C is greater than or equal to 1. If not draw a triangle ABC and then verify with the addition
