To determine how many triangles exist with the given angle measures, we can use the Triangle Inequality Theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's assume that one of the angles in the triangle is 43°. The sum of the other two angles must be greater than 180° - 43° = 137° in order for a triangle to form.
If the other two angles are both 43°, their sum is 43° + 43° = 86°, which is less than 137°. Therefore, it is impossible to form a triangle with two 43° angles.
Let's try another scenario: if two angles are 94°, their sum is 94° + 94° = 188°, which is greater than 137°. In this case, a triangle can form.
However, we still need to consider the remaining angle. For a triangle to exist, the third angle must be between the sum and difference of the other two angles.
The sum of the two known angles is 94° + 94° = 188°, and the difference is 94° - 94° = 0°.
Since 43° is between 0° and 188°, a possible triangle can be formed with angles measuring 43°, 43°, and 94°.
Therefore, only one triangle exists with the given angle measures.
