I need some help understanding how to get the value of 'x'. The angle is 17 degrees and the book gives an answer of 0.90375.
Please see attachment for diagram.
Because, in traingle QMC:
angle QCM = theta = 17 degree
MC = 1.125
QM = 1.125*tan(17) = 1.125*0.30573 = ...
This solution contains step-by-step trigonometry calculations to determine value of x.
