Answer:
137°
Step-by-step explanation:
If we know that a set of angles form one of these special relationships, we can determine the measure of the other angle. To determine the supplement, subtract the given angle from 180. 180 - 43 = 137° The supplement of 43° is 137°.
19, cuz 4x19 is 76 and 72<76
Yes, an angle less than 90 degrees is acute.
1,2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60.
