9 degrees
Since the internal angles of a triangle always add up to 180... 180=5x+3x+x is the same as 180=9x - therefore 180 divided by 9 equals 20. The three angles are 100, 60 and 20 degrees respectively.
The value of sine and cosine varies between -1 and 1, it never can be 12. If you mean .12, then we have: sin x = .12 x = sin-1 .12 x = 6.89 degrees So that, cos x = cos 6.89 = .99
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
if the angle at a equals X then the angle at b equals X+40 and the angle at c equals X+20 the sum of the angels in a triangle is 360 degrees so: X + X+40 + X+20 = 360 3X + 60 = 360 3X = 300 X = 100.

The answer will depend on what x is!
The angle or arc that when added to a given angle or arc equals a right angle in measureThat is, for any angle x less than 90º, the complement of xº = (90 - x)º. For example, the complement of 15º is (90 - 15 =) 75º.Here's a related answer for free: the supplement of an angle x is 180º - x.
X = 180 - Y so 180 - Y = 2x + 4 and Y = 4x + 20 so 180 - 4x - 20 = 2x + 4 therefore 6x = 156 so x = 26 making Angle X = 56o and Angle Y = 124o
Since the internal angles of a triangle always add up to 180... 180=5x+3x+x is the same as 180=9x - therefore 180 divided by 9 equals 20. The three angles are 100, 60 and 20 degrees respectively.
It means the ratio of the opposite angle to the hypotenuse of a triangle for angle "x". This is for a right triangle.
you put it at a 90 degree angle
Equals sin x divided by cos x. In a right-angled triangle it is the ratio of the two shorter sides, the one opposite the angle called x, divided by the the side closest to x.
it equals 90 degrees and the two rays that make it are perpendicular,so it's a square corner
Angle A = 90 degrees = 5x + 50 So 5x = 40 or x = 8
