13. a vertical flagstaff is on the top of a building
which stands on level ground. from a point p
on ground level the angle of elevation of the top
of the flagstaff is observed to be 32%, and the
angle of elevation of the bottom of the flagstaff
to be 29º. from a point q on ground level,
75 m closer to the building, the angle of eleva-
tion of the top of the flagstaff is 38°.
calculate to three significant figures:
(a) the distance of p from the base of the
building
(b) the height of the building
(c) the length of the flagstaff.

Finally, the arena decides to offer advertising space on the jerseys of the arena’s own amateur volley ball team. the arena wants the probability of being shortlisted to be 0.14. what is this as a percentage and a fraction? what is the probability of not being shortlisted? give your answer as a decimal. those shortlisted are entered into a final game of chance. there are six balls in a bag (2 blue balls, 2 green balls and 2 golden balls). to win, a company needs to take out two golden balls. the first ball is not replaced. what is the probability of any company winning advertising space on their volley ball team jerseys?
