If it's a perfect square, then it's easy. However, if it's not a perfect square, use the square root button on your calculator. IF you happen to know calculus then you could use Newton's Method....but I'm thinking you're not there yet. So stick with the calculator.
Step-by-step explanation:
We know:
The sum of the measures of acute angles in a right triangle is equal 90°.
Therefore
(1) A + B = 90°
(2) 90° + B + C = 180° - angles on a straight line
(3) from (2) B + C = 90° → B = 90° - C
(4) from (1) and (3) A + (90° - C) = 90° → A - C = 0
Therefore
A = C → ∠A ≅ ∠C
