PRACTICE TUTORIAL (Trigonometry)
1 If cos 20" - m, express the following in terms of m. A
diagram can be useful
1.1 tan 20
1.2 cos 110​

4. find the geometric mean of 4 and 12. 24 8

Given: ac and db are diameters. m∠3=

Tell me how you got the it use the figures to answer questions 1and 2. in each diagram, line k is parallel to line l, and line t intersects lines. 1. based on the diagrams, what is the value of x? 2. how would you verify your answer for x?
