while standing at the left corner of the schoolyard in front of her school, Suzie estimates that the front face is 8.9m wide and 4.7m high. from her position, Suzie is 12m from the base of the right exterior wall. she determines that the left and right exterior walls appearto ne 39 degrees apart. From her position, what is the angle of elevation, to the nearest degree, to the top of the left exterior wall?

from her feet, or eyes?

Too many unknowns.
What shape is the schoolyard?
Does it extend beyond the side walls of the school?
Can't see what the left corner has to do with anything.
There's a whole circle of points that are 12m from the front base of the right wall.
Draw a diagram, label all corners of the school, label Suzie's positions, so we can fix them in our mind.
Then come on back. Who knows, the systematic labeling of the diagram may show how it can be solved...
