Question

If sin 30° + cos 45° = x, then the value of x. solution

Answer 1

Hi there,

Question : sin(30°) + cos(45°) = x thus find x.

Solution :
Since, sin(30°) = 1/2 and cos(45°) = 1/√2
Therefore,
Sin(30°) + cos(45°) = 1/2 + 1/√2
Sin(30°) + cos(45°) = (1+√2)/2 = x

Therefore,
x = (1+√2)/2 (ans)


Hope it helps you.
Thank you.
