How to solve pythagoras theorem?
From the given triangle in the brainly link, we can deduce the correct steps through pythagoras theorem as:
Step 1; a² + 7² = 25²
Step 2; a² + 49 = 625
Step 3; a² = 576
Step 4; Taking square roots of both sides of step 3 gives us;
a = 24
Thus, the step in which Shawna make an error is in Step 2 because She incorrectly squared the numbers.
