By the sine rule,

sin(C)/c = sin(B)/b

so sin(C) = 25/15*sin(32d15m) = 0.8894

so C = 62.8 deg or 117.2 deg.

Therefore, A = 180 - (B+C) = 85.0 deg or 30.5 deg

and then, using the sine rule again,

a/sin(A) = b/sin(B)

so a = sin(A)*b/sin(B) = 28 or a = 14.3

Does a right angled triangle is one angle always a right angle?

Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.

How do you calculate the missing degree of a triangle?

The sum of all the angles in a triangle equals 180o. To find the missing angle, subtract the sum of the two known angles from 180o.ExampleTwo angles of a triangle are 35o and 62o. What is the third angle?Solution180o - (35o + 62o) =180o - 97o = 83o
