(a) Make m the subject of the relations $h=\frac{mt}{d(m+p)}$.
(b)
In the diagram, WY and WZ are straight lines, O is the centre of circle WXM and < XWM = 48°. Calculate the value of < WYZ.
(c) An operation $\star$ is defind on the set X = {1, 3, 5, 6} by $m\star n=m+n+2(mod7)$ where $m,n\in X$.
(i) Draw a table for the operation.
(ii) Using the table, find the truth set of : (I) $3\star n=3$ ; (II) $n\star n=3$.
