A 75 degree angle.
It is an acute angle
Use a protractor and a straight edge to construct a 75 degree angle
15 degrees
It is a right angle triangle and angle A measures 15 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.
It is an acute angle
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
75 degrees
105 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.
