In this specific example one would use the Law of Cosines. The Law of Cosines is defined as:
* a2 = b2 + c2 - 2bc(cos(A)) In this case, we need to switch the formula to fit our sides:
* c2 = a2 + b2 - 2ab(cos(C)) Now, we just input are given numbers into the equation:
* c2 = (10)2 + (15)2 - 2(10)(15)cos(62o) Make sure your calculator is in degree mode when solving this equation.
* c2 = (100) + (225) - (300)cos(62o) * c2 = 325 - 140.84 * c2 = 184.16 (Square root each side)
* c = 13.57

What is the measure of angle A in triangle ABC if B equals 15 degrees C equals 65 degrees and side a equals 19?
If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation. Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees

Can triangle abc be a right triangle if side ac2 side bc3 and side ab4?
No.
What is the scale factor of triangle ABC to triangle XYZ?
The scale factor of triangle ABC to triangle XYZ can be determined by comparing the lengths of corresponding sides of the two triangles. To find the scale factor, divide the length of a side in triangle ABC by the length of the corresponding side in triangle XYZ. If all corresponding sides have the same ratio, that ratio is the scale factor for the triangles.
Which side lengths form a triangle that is similar to triangle ABC?
Any triangle whose sides are in the same ratio with the corresponding sides of ABC.
