Answer:

R = 5 ft

Step-by-step explanation:

Pythagorean theorem

x² + 12² = (x + 8)²

x² + 144 = x² + 16x + 64

       16x = 80

          x = 5

A triangle has side lengths of 13, 9, and 5. Is the triangle a right triangle? Explain.
valentina_108 [34]

Answer: This triangle is <u>not</u> a right triangle

Step-by-step explanation:

In a right triangle, the hypotenuse(c) is always the longest side and a and b are the shorter sides.  Thus, 5^2+9^2=13^2.  Simplify this to get 25+81=169, then 106=169.  Because 106 does <u>not</u> equal 169, it is not a right triangle.
