In the figure, PQRS is a circle with ST||RQ. Find the value of x if PT = pS
70o
55o
40o
35o
Correct answer is B
< PST = < RQT = x(corresponding angle)
< PST = < PTS = < PTS x (PS = PT0
< SRQ = < SPT = 180o (sum of < on straight line)
< SPT = 180o - 110o = 70o
in < SPT, < PST = PTS = < PSt = 180o
2x + 70 = 180o
2x = 180o - 70o = 110o
x = \(\frac{110^o}{2}\) = 55o
34o
42o
52o
76o
Correct answer is C
< EFH = < EGH = 34º (angles n the same segment)
< GHF = < GEF = 42º(angles in the same segment)
< FOG = 42 + 34 = 76º (exterior angle)
< FOG = < EOH = 76º (vertically opposite angle)
< EDO = 90º, < DOE = \(\frac{76}{2}\) = 38º
< HEG = 90º - 38º = 52º
the shaded portion in the graph is represented by
y + x - x \(\leq\) 0, y - x \(\leq\) 0
y - x + x, 3 \(\leq\) 0, y - x \(\geq\) 0
y + x - 3 \(\geq\) 0, y + x \(\leq\) 0
y - x + x3 \(\geq\) 0, y + x \(\leq\) 0
Correct answer is C

\(\begin{array}{c|c} x & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\ \hline f & 1 & 9 & 4 & 7 & 10 & 8 & 7 & 9 & 8 & 2 & 1\end{array}\)
no pupils who failed the test = 1 + 3 + 4 + 7 + 10
= 25
5 of pupils who fail = \(\frac{25}{60}\) x 100%
= 41.70%

Correct answer is B
Let the monthly expenditure on school fees be x let the monthly expenditure on housing be 2x; angle of housing and school fee in a pie chart = 360o - (120o + 90o)
= 360o - 210o = 150o
Angle of housing in a pie-chart = \(\frac{2}{3}\) x 150 = 100
\(\frac{100}{360}\) x 7200 = N2,000
