In \(\bigtriangleup\)XYZ, determine the cosine of angle Z.
\(\frac{3}{39}\)
\(\frac{29}{36}\)
\(\frac{14}{5}\)
\(\frac{7}{5}\)
Correct answer is B
cos z = \(\frac{y^2 + x^2 -z^2}{2yx}\)
= \(\frac{9 + 36 - 16}{2(3)(6)}\)
= \(\frac{29}{36}\)
29 x 104
26 x 104
16 x 104
13 x 104
Correct answer is B
15 - 29 years is represented by 104o
Number of people in the group is \(\frac{104}{360}\) x 0.9m
= 260000 = 26 x 104
In the figure, PQ||ST, RS||UV. If PQR = 35o and QRS = 65o, find STV
30o
35o
55o
65o
Correct answer is A
Draw XW//PQ and ARW = 35o (alternative angle)
WRS = 60 - 30
= 30o
RSR = 30o (Alternative angle)
STV = 30o (Alternative angle)
20o
55o
75o
140o
Correct answer is C
Given \(\bigtriangleup\) isosceles PQ = QT, SRQ = 35o
TPQ = 20o
PQR = is a straight line
Since PQ = QT, angle P = angle T = 20o
Angle PQR = 180o - (20 + 20) = 140o
TQR = 180o - 140o = 40o < on a straight line
QSR = 180o - (40 + 35)o = 105o
TSR = 180o - 105o
= 75o
In the figure, PQRS is a circle. If chords QR and RS are equal, calculate the value of x
80o
60o
45o
40o
Correct answer is D
SRT is a straight line, where QRT = 120
SRQ = 180o - 120o = 60o - (angle on a straight line)
also angle QRS = 180o - 100o (angle on a straight line) . In angles where QR = SR and angle SRQ = 60o
x = 100 - 60 = 40o
