There are a number of triangles that can be constructed with the angles measuring 10º, 80º, and 90º because the side lengths are not given.
Given :
Angles measuring 10º, 80º, and 90º.
The following steps can be used in order to determine the total number of triangles that can be constructed with angles measuring 10º, 80º, and 90º:
Step 1 - Let the triangle be constructed with base angles 10º and 80º. The vertex angle is 90º.
Step 2 - Now, another triangle can be constructed with base angles 80º and 90º. The vertex angle is 10º.
Step 3 - There are a number of triangles more that can be constructed with the angles measuring 10º, 80º, and 90º because the side lengths are not given.
Therefore, the correct option is A) more than one.
