How does 5 12 13 make a right angle?

By Pythagorean theorem, if the sum of squares of smaller sides of a triangle equals the square of longest side, it is a right angle triangle where the long side is the hypotenuse. 5 squared plus 12 squared is equal to 13 squared

What is the sin of angle B if the angles are 3 4 5?

I think you have not asked the question correctly.I guess you meant that the sides of the triangle are 3, 4 and 5. Similarly you have given no indication of which angle is opposite which side.A 3, 4, 5 triangle is a right angle triangle (5 is the hypotenuse).Thus depending where angle B is, its sine will be:If B is opposite the side of length 3, sin B = 4/5If B is opposite the side of length 4, sin B = 3/5If B is opposite the side of length 5, sin B = 5/5 = 1; alternatively ∠B = 90° and sin B = sin 90° = 1
