To find the measure of the third angle of a triangle, you can use the fact that the sum of all three angles in a triangle is always 180 degrees. So, if one angle measures 50 degrees and the other measures 85 degrees, you can subtract their sum from 180 to find the measure of the third angle. Therefore, the third angle would measure 180 - 50 - 85 = 45 degrees.
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
