anonymous · Answer

first find the length of KL using the area

anonymous · Answer

48/6

anonymous · Answer

Can't you just divide the area in half since it is made up of 2 triangles?

anonymous · Answer

you need to find the side length though

anonymous · Answer

itd be 8

anonymous · Answer

ok now we have the opposite and adjacent sides of the triangle

anonymous · Answer

we can now find the angle using tan(theta)=opposite/adjacent

anonymous · Answer

i have no idea how to do the tan

anonymous · Answer

$$\theta=\tan ^{-1}(6/8)$$

anonymous · Answer

just plug that into your calculator

anonymous · Answer

0.75

anonymous · Answer

nope, make sure your calculator is in degree mode

If you got an apple product, just go to their calculator. O n the phone, turn it sideways and you should see tan.
