The sine of a complementary angle can be found using the relationship that the sine of an angle is equal to the cosine of its complement. Since the complementary angle of 28 degrees is 62 degrees (90 - 28 = 62), the sine of 62 degrees is equal to the cosine of 28 degrees. Therefore, (\sin(62^\circ) = \cos(28^\circ)).

A right triangle has 28 degrees angle what are the measures of the other angles?
Well, well, well, aren't we feeling all mathematical today? If one angle is 28 degrees in a right triangle, the other acute angle must be 62 degrees (90 - 28 = 62). As for the right angle, it's a whopping 90 degrees. Math can be a real trip sometimes, can't it?

It is 90-28 = 62 degrees
The measure of an angle is 28 degrees greater than its complement find the measure of each angle?
Suppose the larger angle is x degrees. Then the smaller angle is x - 2 degrees, and so they sum to 2x - 28 degrees. The two angles are complementary, so 2x - 28 = 90 is 2x = 90 + 28 = 118 so that x = 118/2 = 59 degrees and then x - 29 = 59 - 28 = 31 degrees. The two angles are 59 and 31 degrees.

90 - 28 = 62 degrees.

What does sin 28 look like?
The sine of 28 degrees, or sin(28°), represents the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle. Its approximate value is 0.4695, indicating that if the hypotenuse is 1 unit long, the opposite side would be about 0.4695 units long. Graphically, sin(28°) can be represented on the unit circle as the y-coordinate of the point corresponding to 28 degrees.
An angle measures 62 degrees what is the measure of its complement?
The difference between 90 degrees and an angle is its complement. 90 - 62 = 28 degrees.
