Solution of trianglesAfter a bad storm, the bridge across the river along a nature trail was destroyed. Surveyors need to measure the exact distance because it will be difficult to get supplies to the site. They determine spots A and B will be the start of the bridge on either side due to regular flooding of the river.
. One surveyor stands at spot A and measures the angle to another surveyor at points B and C. The angle at A is 27º.
. The surveyor on the other side measures the angles at B and C as well at the distance between them. Angle B is 105° and angle C is 48°. The distance from B to C is 125 feet.
