Step-by-step explanation:
First find the angle BAC
BAC= 180 -(90+50) ( interior angle of triangle is 180)
BAC= 180- 140
= 40 degrees
sin 40= opposite/ hypotaneus
sin 40 = 2/ hyp
0.6427 = 2/ hyp
hypotaneus = 2/ 0.6427
hypotaneus = 3.1118
AB= 3.1118
to nearest hundredth = 3.11
You go through and square each term in the parentheses
(12a^2b^6)^2 = (12)^2(a^2)^2(b^6)^2 =
144a^4b^12
29 because the original answer would have been 28.26

Ratio is 7:9
add the ratio it becomes 16
272 members divided by 16
that makes it 17 per one ratio
women ratio is 9
17x9 is 153
i=153 women in the sports club
same thing with ii except it’s divided by 7
91/7 is 13
which means 13 per ratio
there are 9 ratios of women
9x13=117
ii=117 women in a sports club with 91 men with a ratio of 7:9
