Sum means to add up, so 60 + 90 = 150
69factors of 69:1, 3, 23, 69
69% of 90= 69% * 90= 0.69 * 90= 62.1
This is simple to figure out: Add all of those numbers together and then divide it by how many numbers you added up. Use a caculator if you have to.

69 x 90 = 6210
Supplementary angles are angles that add up to 180°. i.e. 75° +105°= 180° or 120°+60°=180° Complementary angles add up to 90° i.e. 30°+60°= 90° or 75°+ 15°=90°
1x30=30 2x30=60 3x30=90 4x30=120 5x30=150 6x30=18030, 60, 90, 120, 150 and so on.
180. 90 = 2 x 32 x 5 60 = 22 x 3 x 5 lcm = 22 x 32 x 5 = 180
69 is 115% of 60.
It is: 60 degrees because complementary angles add up to 90 degrees
