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 degrees angle equals what?
the sine of a 30 degree angle is 0.5
How do you find the radius of a circle if the central angle is 36 degrees and the arc length of the sector is 2 pi cm?
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.
What is the area of a triangle if angle a equals 42 degrees angle b equals 87 degrees and angle c equals 24 degrees?
A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
What is the length of BC in this triangle angle BAC equals 40 degrees and angle ABC equals 50 degrees and angle BCA equals 90 degrees .?
In order to find length BC the length of AC or length of the hypotenuse must be given
What angle equals 95 degrees?
An angle of 95 degrees is an obtuse angle.
If Angle A equals 83 degrees and angle B equals 15 degrees find angle C?
82 degrees (180 degrees in a triangle)
Right angle equals how many degrees?
A right angle equals 90 degrees
If a triangle has an angle A equals 70 degrees and angle B equals 55 degree what is angle C?
55 degrees.
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals?
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
What angle equals 120?
An angle of 120 degrees is an obtuse angle
What angle equals 90 degrees?
A right angle .
What is a complimentery angle?
a angle that equals 90 degrees
Which angle equals 60 degrees?
An acute angle
If a triangle has an angle A equals 60.5 degree and angle b equals 69.5 degrees what is angle C?
Angle C = 50 degrees. ------------------------------- A triangle equals 180 degrees. 60.5 + 69.5 = 150 180-150 = 50.
What angle equals 140 degrees?
An angle that equals 140 degrees would be considered an "obtuse" angle. This is because it is greater than 90 degrees but does not exceed a straight line of 180 degrees.
