Points X and Y are respectively 12m North and 5m east of point Z. Calculate XY
7m
12m
13m
17m
18m
Correct answer is C
Using pythagora's theorem:
hyp\(^2\) = opp\(^2\) + adj\(^2\)
hyp\(^2\) = 12\(^2\) + 5\(^2\) → 144 + 25
hyp\(^2\) = 169
hyp = √169
hyp = 13

5√3m
10m
Correct answer is C
The ladder makes 60° inclination with the wall and its foot is 5m away from the wall.
Sketching the diagram, you will see that we have
\(sin 60 = \frac{5}{x}\) (where x is the length of the ladder)
⇒ \(x = \frac{5}{sin60}\)
\(x = \frac{10\sqrt{3}}{3}m\)
30km

\(-\frac{1}{2}\)
\(-\frac{\sqrt{3}}{2}\)
\(\frac{1}{2}\)
\(\frac{\sqrt{2}}{2}\)
\(\frac{\sqrt{3}}{2}\)
Correct answer is A
sin 210 = - sin (210 - 180) = - sin 30
= \(-\frac{1}{2}\)
