find the height of a vertical cliff if the angle of elevation is 25 degersto the top from a point ehich is 235m from the base of the cliff
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
