ABCDE is a pentagon. The angles A, B, C, D, and E are x°,<br />
2x°, 3x°, 4x°, and 120°. Find the value of x.<br />
25. In the diagram, not<br />
drawn to scale, angles<br />
BAC = 24°, EDC = 30°<br />
and angle CED = x°.<br />
Calculate in terms of x<br />
the size of<br />
i. Angle AFD<br />
ii. Angle BFE<br />
iii. Hence deduce the<br />
value of x.<br />
26. Given that π radians = 180° express<br />
i.<br />
<br />
radians in degrees<br />
6<br />
ii. 210° in degrees<br />
