No because a triangles inner angles must equal a whole 180 degrees and an equilateral has to have all equal interior angles and 75+75+75 does not equal 180
An angle is supplementary to another if their measures add up to 180 degrees. To find the angle that is supplementary to a 75-degree angle, subtract 75 from 180. Therefore, 180 - 75 = 105 degrees. Thus, the angle that is supplementary to a 75-degree angle is 105 degrees.
Two angles that have measures that sum to 180 degrees are called supplementary angles. For example, a 30-degree angle and a 150-degree angle are supplementary because 30 + 150 = 180. Similarly, a 75-degree angle and a 105-degree angle are also supplementary, as their measures add up to 180 degrees.
No because the 4 interior angles must add up to 360 degrees

A 75 degree angle.
The supplement of a 75-degree angle is the angle that, when added to 75 degrees, equals 180 degrees (a straight line). To find the supplement of a given angle, you subtract the given angle from 180 degrees. Therefore, the supplement of a 75-degree angle is 105 degrees.
Use a protractor and a straight edge to construct a 75 degree angle
15 degrees
180-75=105 degrees
The third angle is 68 degrees which makes it a scalene triangle
105 degrees
75 degrees
Complementary angles total 90°. The complement (or complementary angle) of 15° is 75° (90 - 15).
The supplementary angle of 57 degrees is 123 degrees The complementary angle of 75 degrees is 15 degrees So: 123 minus 15 = 108 degrees
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 105 degree angle is equal to 180 - 105 = 75 degrees.
Use a protractor.
