Questions 6 to 9 refer to a right pyramid with rectangular base ABCD and vertex M. O is the centre of the base so that OM is the height of the pyramid. ✓ Use the method demonstrated in Worked Example 5.14 to find the required lengths and angles. 6 a AC=5 cm, OM= 6 cm. Find angle ACM. b AC=9cm, OM= 4 cm. Find angle ACM. 7 a AB=5 cm, BC = 7 cm, OM= 5 cm. Find angle ACM. AB=4mm, BC= 8mm, OM= 5 mm. Find angle b ACM. A M B C
