In a triangle a/SinA = b/SinB = c/SinC
Since angle A = 43 and angle C is 72, angle B = (180) - (72 + 43) = 65
Hence 20/Sin65 = c/Sin72
20/0.9063 = c/0.9510
c = (20 x 0.9510)/0.9063 = 20.9864

the sine of a 30 degree angle is 0.5

The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
In order to find length BC the length of AC or length of the hypotenuse must be given
An angle of 95 degrees is an obtuse angle.
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. The complement of an angle is the angle that, when added to the original angle, equals 90 degrees. Therefore, the supplement of the complement of a 38-degree angle would be the angle that, when added to the complement of 38 degrees (52 degrees), equals 180 degrees. This angle would be 128 degrees.
82 degrees (180 degrees in a triangle)
A right angle equals 90 degrees
55 degrees.
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
An angle of 120 degrees is an obtuse angle
A right angle .
a angle that equals 90 degrees
An acute angle
Angle C = 50 degrees. ------------------------------- A triangle equals 180 degrees. 60.5 + 69.5 = 150 180-150 = 50.
