Bus stop method. 3 goes into 4 once. Remainer 1. Add that to the 5. Makes 15. 3 into 15 goes 5 times. No remainder. 3 goes into 9, 3 times and no remainer. So 459/3 is 153
Answer:
75
Step-by-step explanation:
The measure of two supplementary angles = 15:21
The angles are 15x , 21x
15x + 21x = 180 {Supplementary}
36x = 180
x = 180/36
x = 5
Smallest angle = 15 * 5 = 75
