To determine if the triangle with side lengths 9 in., 15 in., and 19 in. is acute, obtuse, or right, we can use the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the length of the hypotenuse is 19 in. and the lengths of the other two sides are 9 in. and 15 in.
If the Pythagorean theorem holds true, then 9^2 + 15^2 should be equal to 19^2:
81 + 225 = 361
Since 81 + 225 is equal to 361, we can conclude that the triangle is right.
Therefore, the answer to the first question is:
• Right
To solve for x in the second question, we need more information about the triangle. Please provide the necessary data for further calculation.
