(b)
A vertical flagpole, AF, is 9m high.
It is held in place by two straight wires FG and FH.
FG = 20m and AH = 24m.
G, A and H lie in a straight line on horizontal ground.
Calculate
(i) angle FHA,
(ii) the distance GA.
Answer/Explanation
(a)(i) 90+53+\(\angle ABC\) =180
\(\angle ABC\)=180-143
\(\angle ABC\)=37
Now, d=120 Cos 37\((37)^/circ\)
=120\(\times0.7986\)
=95.84
(ii) Bearing means angle measured clockwise from north.
= 233
(b)(i) \(\angle FHA\):
FH=\(\sqrt{(24)^2+(9)^2}\)
=\(\sqrt{576+81}\)
=\(\sqrt{657}\)
= 25.63
\(tan \theta=\frac{9}{24}\)
\(\theta\) = \((\tan)^{-1}(\frac{9}{24})\)
= 20.55
(ii) Distance GA:-
\((20)^2\)=\((GA)^2+9^2\)
GA=\(\sqrt{400-81}\)
= \(\sqrt{319}\)
= 17.9
