Answer:
There are two triangles possible.
Explanation:
We are asked the number of triangles we can draw with angles measuring 50°, 90° and 40°.
Since, the angles of the triangle are unique and it is a right triangle therefore, we can consider the base angle as 50° and the remaining angle becomes 40° and we also consider the base angle as 40° and the remaining angle becomes 50°.
So, there are two triangles possible. (Answer)
