Answer: Side (RT) is equal to 13
Step-by-step explanation:
You can use the Pythagorean theorem on this question because this is a right triangle.
Formula: a^2 + b^2 = c^2
Step 1: Plug in your numbers
5²+12²=c²
Step 2: Simplify
25+144=c²
(can reduce to)
169=c²
Step 3: Square 169
√169 = 13
The length of side (RT) is 13
