    or, if another acute angle is also 54°, then the 3rd angle is
180 - 2*54 = 72°
    
180 - 2*54 = 72°

    Since the triangle is isosceles, the other two angles must be congruent. Let x be the measure of one of the congruent angles.
Using the fact that the angles in any triangle add up to 180 degrees, we can write:
54 + x + x = 180
Simplifying the left side, we get:
54 + 2x = 180
Subtracting 54 from both sides, we get:
2x = 126
Dividing both sides by 2, we get:
x = 63
So the measure of one of the other angles could be 63 degrees.
