<span>sin 90° = 1
</span>
cos 0° = 1
There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>
So : cos 0° = sin (90° - 0°) = sin 90° = 1
No, this is not true, 22+32 =54 this is not a true statement
Answer:
that means you need to find the surface area, but not the part that is touching the ground or the bottom.
