Find the area

***[isuru]*** · Answer

Hi,
 $$area = (\frac{ length \ of \ the\ base + length \ of \ the \  upper side \  }{ 2 } ) * height$$

***[isuru]*** · Answer

so...
 in ur case...
 length of the base = 7 m
 length of the upper side = 5m

anonymous · Answer

Hey, I know the formula... but I need to find the height. I'm not sure how to find the height when there's an angle...

***[isuru]*** · Answer

to find height u have to use trigonometric ratios. r u familiar with that ?

anonymous · Answer

Umm, not really... could you explain?

Oh, so the sin value of 45 degrees would be 0.70710678, correct?

***[isuru]*** · Answer

to be more precise...
       $$\sin \alpha = \frac{ Opposite  \ side \  }{ hypetenus  }$$

So....B/A
Typically I have to have the Sin calculated for me online because it is the most confusing thing that I have ever encountered.
