Best ResponseYou've already chosen the best response.0first, to get the measure of angle B, use the law of sine : a sinB = b sinA sinB = b sinA/a = 24*sin61°/23 = .... ?

Best ResponseYou've already chosen the best response.0after u got the value of sinB, take arc(sin) to get angle B and dont forget use ur calculator :)

Best ResponseYou've already chosen the best response.0well, in my laptop it says the value of sin61 = 0.874

Best ResponseYou've already chosen the best response.0okay, then we have to fine angle B sinB = 0.192 B = arc(sin(0.192)) = 11.069 degrees = 11.07 deg (it is nearest)

Best ResponseYou've already chosen the best response.0@RadEn find if there is one or two triangles

Best ResponseYou've already chosen the best response.0i think it is just one triangle, by verify the measure of angle C C = 180  (A+B) C = 180  (61+11.07) C = 180  72.07 C = 107.93 degrees only one possible for angle C
