the bottom of a wooden plank is 3 ft from wall. find aprox height off the ground where the board touches the wall. round to nearest foot. find aprox length of plank round to nearest foot.

You're missing information here. What is the angle of the plank to the ground, or the plank to the wall?

Ok, so then the angle of the plank to the wall is 49 degrees.

So now we set up the appropriate equation

a) sin49 = 3 / AC

AC = 3 / sin49 = 4.0 ft

b) tan49 = 3 / BC

BC = 3 / tan49 = 2.6 ft

OMGosh...THABNK YOU!!!!!!!!! Im failing math and this is a big help!

I'm so glad I could help :)
