To apply the Pythagorean Theorem, we can use the equation:
\(a^2 + b^2 = c^2\)
where a and b are the sides of the right triangle and c is the hypotenuse.
In this case, the base (a) has a value of 3 and the hypotenuse (c) has a value of 15. We are trying to find the unknown side length (b).
Plugging in the known values into the equation, we get:
\(3^2 + b^2 = 15^2\)
\(9 + b^2 = 225\)
Subtracting 9 from both sides, we get:
\(b^2 = 216\)
Taking the square root of both sides, we find:
\(b = \sqrt{216} \approx 14.7\)
So, the unknown side length is approximately 14.7.
The correct answer is 14.7.
Use the image to answer the question.
A right triangle shows the base with a value of 3, the hypotenuse on the left with a value of 15, and the perpendicular side to the base on the right with a question mark.
Apply the Pythagorean Theorem to find the unknown side length in the given triangle. Round your answer to the nearest tenth.
