Answer: approximately 3.3
step by step:
so for this problem you would use Pythagorean theorem. Because there isn’t a complete side, you would use the hypotenuse and the other side given. The formula is a^2 + b^2 = c^2
You would plug in 3.8 for one sid, either a or b and plug in 10 for c since it’s the hypotenuse. You then get 14.44+b^2= 100. Since you’re trying to get the side by itself, you subtract 14.44 from both sides and not b^2 = 85.56. The final step is to take the square root since we want to get the variable on its own. Once you take the square root of 85.56, the new answer is 9.3 rounded to the nearest tenth. That’s for the whole side, but since it’s asking for the little part not listed, you subtract 6 from 9.3 and your answer is not 3.3. Or should be around there since it’s a decimal.
