MATH YEAR 9

It is a trig question. 

Draw the triangle

Put 25 degrees and 235m in the correct places.

Call the height y      (h for height could be confused with hypotenuse)

Mark the opp, adj and hyp sides

Choose the correct trig function and solve.

If you have specific problems then explain what they are.

----------------------

Oh and do not double post just cause you do not get an immediate answer!!

We know an angle, an adjacent side, and we're looking for the opposite side.....so the tangent seems appropriate....and we have

tan (25)  = opp/ 235   multiply both sides by 235

235 * tan (25)  = opp  =  height  of cliff  ≈ 109.6 m

I like my answer better Chris. 

If the person needed more help I invited them to ask.

The person didn't ask so they must have been happy with my directions. :)
