In the diagram, O is the centre of the circle. OM||XZ and < ZOM = 25º. Calculate ∠XYZ
50o
55o
60o
65o
Correct answer is D
Angle in a semi-circle is 90º when OM is subtended
: (90 - 25)º
= 65º
Find the value of m in the diagram
34o
27o
23o
17o
Correct answer is D
\(\bigtriangleup\) ABC, A + 153 = 180 (angles on straight line)
< A = 180 - 153 = 27
< B = 2m(vertically opposite angles)
< C = 7m (corresponding ngles)
< A + < B + < C = 180 (sum of int. angles of \(\bigtriangleup\))
i.e. 27 + 2m + 7m = 180o
9m = 180 - 27
9m = 153
m = \(\frac{153}{9}\)
= 17
\(\bigtriangleup\) ZYX = \(\bigtriangleup\) OMN
\(\bigtriangleup\) YZX = \(\bigtriangleup\) NOM
\(\bigtriangleup\) ZXY= \(\bigtriangleup\) MON
\(\bigtriangleup\) XYZ= \(\bigtriangleup\) NOM
