2. Angle Addition Postulate as they are adding both angles
3. 60 + 40 = m <ABC because it's a substitution
4. 100 = m <ABC as it is simplified already
5. Definition of obtuse angle
0.4 grams or 0.40 grams however you like writing decimals, but either way they are both the same.
Ratio = 2:3
Let smaller angle be 2x
Let bigger angle be 3x
Sum of two complementary angles = 90
2x + 3x = 90
5x = 90
x = 90/5 = 18
Smaller angle = 2x= 2*18 = 36
I hope it is helpful :D
Compare <span>6:15 30:80
or you can write </span><span>6/15 and 30/80
6/15 = 0.4
30/80 = 0.375
answer </span><span>6:15 > 30:80</span><span>
