If you draw a line perpendicular to side c and intersecting the vertex of angle C, you make two right triangles. Let's call the perpendicular segment side d.
Now the sinB = d/a, so d = a sinB = 24 * sin87° ≈ 23.967.
SinA = d/b, so b = d ÷ sinA = 23.967 ÷ sin42° ≈ 36.

How many degrees are in a supplementary angle?
A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
Which triangle has an angle that measures 45 and 90 degrees?
Well, it doesn't exactly have "an angle that measures 45 and 90 degrees". It has one angle that measures 45 degrees, and another angle that measures 90 degrees. That's an isosceles right triangle. The third angle is also 45 degrees, and the length of each leg is 70.7% of the length of the hypotenuse. .
What is the angle in nearest degrees created by the minute hand and the hour hand at 515?
60 degrees
What is the length of the minor arc if the angle is 30 degrees?
It's 0.524 of the length of the radius.
How do you find the circumference of a circle that has an arc length and angle degree?
The total circumference is (arc length) times (360) divided by (the angle degrees)
What is the length of side c to the nearest whole number if side a 105 and angle A 65 degrees and angle B 37 degrees?
70
The tangent of an angle is 0.8 what is the measure of the angle to the nearest tenth?
tan-1(0.8) = 38.65980825 degrees or 38.7 degrees to the nearest tenth.
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 is the area of a triangel to the nearest whole number if A52 degrees 63 degrees and c 8?
The answer will depend on which angle is 63 degrees, and the measurement units used for c.

60 degrees
What is the longest length of a triangle if its shortest length is 3.6cm when two of its angles are 37.25 degrees and 48.4 degrees?
Largest angle: 93.25 degrees Shortest angle: 37.25 degrees Shortest length: 3.6cm Longest length: 3.6*sin(94.35)/sin(37.25) = 5.93cm to two decimal places
The tangent of an angle is 0.8. What is the measure of the angle to the nearest tenth?
It is: tan^-1*(0.8) = 38.7 degrees
The number of degrees in a angle?
It is a measure of the size of the angle.
What is the length of the minor arc if the angle is 30 degrees?
It's 0.524 of the length of the radius.
