Lets start with 2/3 × 5/6 so first we multiply the numerator with the numerator and then the denominator with the denominator: 2×5 and 3×6 so after we multiply the numerators we get 10 and after multiplying the denominators we get 18 10/18 is our new fraction next we have 10/18 × 14 so we multiply 14 with the numerator and we get our new numerator of 140 and our new fraction is 140/18 which also means 140 ÷ 18 now 18 can go into 140 only 7 times as a whole but then afterwards there is a remainder of 14 so 140/18 = 7 14/18 but 14/18 can be simplified since the have a GCF of 2 so you divide the numerator and denominator by 2 and get 7/9 7 7/9 is your answer i hope this helps
Supplementary angles sum up to 180°, suppose the supplement of 161° is x. Then 161+x=180 solving for x we subtract 161 from both sides 161-161+x=180-161 x=19 thus the supplement is 19°
