Re: Compute the solution:

Hi bobbym,

The solutions 124 and 125 are correct. Brilliant!

126. If the centroid of a triangle is at (1,3) and two of its vertices are (-7,6) and (8,5), then find the third vertex of the triangle.

127. Find the angular elevation (angle of elevation from the ground level) of the sun when the length of the shadow of a 30 meter long pole is

meters.
