The pie chart above shows the statistical distribution of 80 students in five subjects in an examination. Calculate how many student offer Mathematics.

A.

30

B.

11

C.

50

D.

20

Correct answer is B

5x° + (16x - 24)° + 5x° + (4x + 12)° + (6x + 12)° = 360°

36x° - 24 + 12 + 12 = 360°

36x° = 360°

x° = \(\frac{360°}{36}\)

= 10°

Thus, the angle of sector representing Mathematics is 5 x 10° = 50°. Hence the number of students who offer mathematics is

\(\frac{50}{360} \times 80 \approx 11\)

The value x in the figure given is

A.

110o

B.

100o

C.

70o

D.

130o

Correct answer is D

Sum of the angles in a triangle = 180°

180° - x + 60 + 70 = 180

130° - x = 180° - 180° = 0°

x = 130°

In the diagram given, find the value of x.

A.

30o

B.

40o

C.

45o

D.

15o

Correct answer is B

In the diagram above, < CDE = < CED = 15o

(base < s of isos. \(\bigtriangleup\))

< ECD = 180o - (15 + 15)o

= 180o - 30o = 150o

But x + 110o = 150o

(Sum of opp. interior < s of a\(\bigtriangleup\) = opp. exterior < )

x = 150o - 110o = 40o
