there are 180 degrees in a striaght line
90-73 = 17 degrees
150 degrees
A reflex angle must measure more than 180º and must be less than 360º.The easiest way to measure a reflex degree is to measure the smaller angle.Then subtract the smaller angle measure (in degrees) from 360º to find the reflex angle measure.A reflex angle is greater than 180 but less than 360 degrees
180 - 143 = 37 degrees
The measurement of angle ABD is 73 degrees. You find this angle by subtracting angle DBC from angle ABC, or 89-16 is equal to 73 degrees.

A protractor is nused to measure angles in degrees.
30 degrees
60 degrees and 120 degrees
It is 180 -64 = 116 and 64 plus 116 = a supplementary angle of 180 degrees
The third angle is 93 degrees
Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.

You measure it very, very carefully!
