Questions 6 to 9 refer to a right pyramid with rectangular base ABCD and vertex M. O is the centre of the base so M 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=9 cm, OM=4cm. Find angle ACM. 7 a AB = 5 cm, BC=7cm, OM=5 cm. Find angle ACM. b AB = 4mm, BC=8mm, OM=5 mm. Find angle АСМ. A В
