-------
Your statement implies the triangle is a right triangle
with hypotenuse = 25
---
The smallest angle is the angle opposite the smallest side, i.e. 7.
---------------------
Ans: angle = arcsin(7/25) = 16.26 degrees

A triangle has side lengths of 7, 24, and 25. What is the measure of the smallest angle of the triangle? (Hint: Use the inverse trig button on your calculator)
Solution:
Let x = smallest angle
The triangle is a right triangle because 7%5E2+%2B+24%5E2+=+25%5E2 [Pythagorean Theorem]
The angle opposite the smallest side is the smallest angle.
sine = (opposite side)/hypotenuse
Hence, sin%28x%29+=+7%2F25
Using the inverse trig button, the sine inverse of 7%2F25%29
Answer: highlight%2816.26%29 degrees [rounded to 2 decimal places]
