Then PLEASE help me out here.. heh
I got a bunch of questions to do, if someone could help me out with the first couple i bet i can figure out the rest myself. I need to know how many cm^2's
here are 3
As for the first one, my guess would be 8:tan(55) which is 5.6. that could be right (then we'd have the hight) etc etc pytagoras. Overal answer 28cm^2
As for the 2nd one, i really don't know :(
If anyone would care to help me out here, please write down everything you do step by step.
Robin :( |

Ever try looking at ur ing notes you stupidass? Or maybe you were just being a dumb and decided not to take any. And you can't do it if nothing was taught to you. :haha: |

w8...it was the area... the law of cosines is good here.
A^2 = B^2 + C^2 - 2*BC*cos(a)
a is the angle and A is the side opposite the angle. B,C are the 2 other sides.
edit: area formula instead, look below.. :p |

| you can't use tan for the 1st triangle since its not a right-angle triangle. you have to use the sine and cosine formulas for all 3. |

in 3 the angles worth 77.5 each.
I cant find out how to do 1,2.sorry
edit: oh I got an idea wait 5 min... |

Heh, I forgot the Area formula... *slaps forehead*
Area = (B*C*sin(a)) / 2
look above for definition. |
