C minus B equals AB
associative property
2
If AC equals 6 and BD equals 4, then AB equals 5.
36
Since 36=24+1/2.24 and abc and pqr are similar, ab= 10+1/2.10=15.
24
yes
By use of the sine rule: sin A / BC = sin B / AC = sin C / AB Angles B and C are known, as is length AC, so: sin B / AC = sin C / AB AB = AC x sin C / sin B AB = 17cm x sin 24 / sin 95 ~= 6.94cm The ratios for the sine rule can also be given the other way up: BC / sin A = AC / sin B = AB / sin C (I learnt the rule the first way.) Further, if r is the radius of the triangle's circumcircle, then: sin A / BC = 1/2r or BC / sin A = 2r
