The measure of an an angle is 75 degrees what is the measure of its complementary angle

The measure of it's complementary angle is 15 degrees.

Step-by-step explanation:

Two angles are complementary when they add up the 90 degrees. This means that the complementary angle plus 75 equals 90, so

x + 75 = 90 | Subtract 75 from both sides

x = 15

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
