The figure shows two right triangles. That is, angles CAO and BCO are right angles. You may assume the following side lengths: AC = 18, BC = 18, and AO = 13. Determine angle AOB in radians. Decimal approximations will be marked incorrect. Symbolic trigonometric expressions such as arctan(5) are accepted. AOB == radians B C
