Given that sin0= 1/4,0 < 0 < pi/2 , what is the exact value of cos 0 (picture provided)

Option b

Step-by-step explanation:

By definition we know that:

We know that for this case:

Then:

Apply square root on both sides of the equation

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

5x+10 is the correct one

hope this
