The bones which has been observed to have sinuses in individuals include the following:
<h3>What is Sinus?</h3>
They are found in the neurocranium part of the body and comprise of system of hollow cavities which form part of the skull which serves as the protective structure of the brain and other organs such as the eyes, nose etc.
The sinus helps to insulate the brain as a result of the delicate nerves which run through it .It also provides the mechanical rigidity of the head which is a vital part of the body.
The bones which have sinuses are the frontal, ethmoid bones etc and are found in the skull region of individuals thereby making it the most appropriate choice.

Sin and cosine of the acute angle are complementary trigonometric functions. This means that between these trigonometric functions, the rule of complementary acute angles applies: sin64° = cos(90°-64°) = cos26°
So, if we have given cos64° = cosx and we want to determine the value of the acute angle x, given the complementarity of the angles to 90 degrees, the required value of the angle x is 26°.
The answer is: x = 26°
