you had to work out the area with 1/2absinC and it said that the area of the triangles added together equaled the area of the rectangle, i then solved it algebraically
hmm the rectangle and triangles was question 14. bearing was last one idk the number, but i think the answer was 98.6 pie chart was like q 20 or q21 i cant remember
the pie chart one was 21 I believe and 20 was the bounds and inequalities I think
