Question

If cos 0+root 2*sin 45+sin A=3,then the value of A is___________.♥

Answer 1

Answer:

90

Step-by-step explanation:

cos 0=1

√2 sin 45=√2×1/√2=1

=>1+1+sin A=3

sin A=1

A = 90

Answer 2

Answer:

cos(0) + $\sqrt{2}$ * sin(45) + sin A = 3

then the value of A is___________.♥

Step-by-step explanation:

Cos(0) = 1 , sin(45) = $\frac{1}{\sqrt{2} }$

So

=> 1 + $\sqrt{2} * \frac{1}{\sqrt{2} }$ + sin A = 3

=> sin A = 3 - 2

=> sin A = 1

=> A = sin^(-1)(1)

=> A = $\frac{\pi }{2}$ =90 degrees
