Question 943012: In triangle ABC, the degree measure of angle A is 20 degree greater than the degree measure of angle B. Angle C is a right angle. What is the measure of angle B?
Since a triangle is 180 & c is 90 the other two sides get split therefore 45 but A is 20 degree more so B should be 25. Is this right

Question 943816: In the triangle below, side BC is 12 units long and side AC is 15 units long. If angle < C is 60 degrees, then what is side AB-squared?
A. 64
B. 81
C. 189
D. 369
E. 549
I tried using the Rule of Cosines, but I'm not getting any of the answer choices.
I did: AB-squared = AC-squared + BC squared - 2(AC)(BC)cos60
(AB)^2 = (15)^2 + (12)^2 - 2(15)(12)cos60
For (AB)^2 = 711.8686

Question 944573: I don't know how to do these problems. The given lengths are two sides of a right triangle. All three side lengths of the triangle are integers and together form a Pythagorean triple. Find the length of the third side and tell weather it is a leg or the hypotenuse. 30 and 40 or 15 and 36, if I could even get one example on how to do them that would be appreciated as I have 8 others to do besides these two.
