What is the sine of a 90 degree angle?
The sine of a 90-degree angle is equal to 1. This is because, in the unit circle, a 90-degree angle corresponds to the point (0, 1), where the sine is defined as the y-coordinate. Thus, sin(90°) = 1.
How many angle formed in 90 degree?
A 90 degree angle is a right angle
How sin90 equals 1?
Because sin = opp/hyp and the opposite side to a 90 degree angle is the hypotenuse.
Does a right angle have a 90 angle?
A right-angle is a 90 degree angleA right triangle has one, and a 90-degree angle isone.
If theres a 90 degree angle and a 40 degree angle what is the other angle?
Fifty degrees. 90+40+90=180
What is the sine of a 90 degree angle?

A 30-60-90 triangle has a hypotenuse of length 44. What is the length of the side opposite the 30 degree angle?
I assume your 90 degree angle is on the right and the 30 degree angle is opposite that. ( degree mode ) sin theta = opposite/hypotenuse sin 30 degrees = opp./44 = 22
What is the relationship between the cos and sin of the non 90 degree angles in a right angle triangle?
sin θ = cos (90° - θ) cos θ = sin (90° - θ)

How sin90 equals 1?
Because sin = opp/hyp and the opposite side to a 90 degree angle is the hypotenuse.
Is 90 angle is right angle?
yes.coz obtuse angle is above 90 degree and below 90 degree is acute.
Does a right angle have a 90 angle?
A right-angle is a 90 degree angleA right triangle has one, and a 90-degree angle isone.
How many degrees does a right angle contain?
A right ange is a 90 degree angle. Within a 90 degree angle, there is only one 90 degree angle, and therefore only one right angle.
If theres a 90 degree angle and a 40 degree angle what is the other angle?
Fifty degrees. 90+40+90=180
