The angle for which the sine value is 0.6691 is found to be 42°.
What is the sine value?
A trigonometric function called sin x, where x is the angle under discussion stands for the sine of an angle. The sine function is the proportion between the perpendicular and hypotenuse of a right-angled triangle. In other words, the hypotenuse and its value change as the angle changes, and it is the ratio of the side opposite to the angle under discussion. In the study of physics, sound and light waves are represented by the sine function.
When the angle between a right-angled triangle's base and hypotenuse changes, the sine's value changes.

Answer:
The expression
can be combined because of the commutative property of addition.
Step-by-step explanation:
A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that

all are examples of monomials.
The commutative property of addition says that changing the order of addends does not change the sum.
If we add
or
, the result will be same.
Therefore,
