Final answer:
The triangle with angle measurements of 87°, 63°, and 30° is a scalene triangle.
Step-by-step explanation:
The triangle with angle measurements of 87°, 63°, and 30° is a scalene triangle.
In a scalene triangle, all three sides have different lengths and all three angles are also different.
This type of triangle does not have any sides that are equal in length, so it is not an equilateral or isosceles triangle.
