The following diagram shows a triangle ABC BC 6 CAB 07 rad

The following diagram shows a triangle ABC. BC = 6, CAB = 0.7 radians, AB = 4p, AC = 3p, where p > 0. Show that p^2 (41 - 40 cos 0.7) = 36. Find p Consider the circle with center B that passes through the point C. The circle cuts the line CA at D, and ADB is obtuse. Part of the circle is shown in the following diagram. Write down the length of BD. Find ADB. Show that CBD = 1.29 radians, correct to 2 decimal places. Hence, find the area of the shaded region.
