SOLUTION: find all the angles in a 5-12-13 triangle.
2013年5月12日 · So, this is a right triangle by the Pythagorean Theorem. It follows that one angle is 90 degrees. So, we need only find the measures of angles opposite 5 and 12. Let's call them a and b. Note that a+b=90. Cos(a)=adj/hyp=12/13 Cos(b)=adj/hyp=5/13 So we want to take ArcCos of 12/13 and 5/13 to find the measures of the remaining angles.

Is 5-12-13 a right triangle? - Homework.Study.com
Is 5-12-13 a right triangle? Pythagorean Triples: In geometry, the Pythagorean Theorem states that if a right triangle has side lengths a , b , and c , where c is the longest side, then a 2 + b 2 = c 2 .
SOLUTION: A 5-12-13 triangle is inscribed in a circle, which is ...
Let the smaller 5-12-13 triangle be ABC with the side lengths of 5, 12 and 13 units. This triangle is a right angled triangle (the fact widely known, since 5^2 + 12^2 = 169 = 13^2). Since this triangle ABC is inscribed in the circle, the hypotenuse of the length 13 units is the DIAMETER of the circle. Thus the radius of the circle is 13/2 = 6.5 ...
