Question

Find the area of the triangle B = 104°, a = 11 cm, c = 18 cm

Answer 1

Area = (ac*sinC)/2

Answer 2

very good nin.

Answer 3

did I interrupt what you were typing, @genius12 ?
sorry!

Answer 4

no lol thats what i was typing except with a small explanation =P

Answer 5

oh yah I was going into details to show the relationship of that area formula with 1/2(bh)

Answer 6

but I have to study for my test tomorrow :P you can do that part for me
medal in advanced!

Answer 7

i'll wait until OP requests for an explanation lol.. @nincompoop

Answer 8

in order to take the sin of C i have to find C. how do i do that?

Answer 9

my bad I meant sinB

Answer 10

Oh okay. Thank you

Answer 11

B* is already given. it's 104°. The area of a generic triangle is given by the length of 2 sides and the angle between them multiplied by 1/2. Here we're given the sides 'a' and 'c' and the angle between them is B = 104°. So it's (1/2)(ac)sin(104°)

Answer 12

I understand now. thanks!
