In the triangle shown, sin θ equals:

• 5/12

• 5/13

• 13/12

• 12/13

• 12/5

The length x is given by:

• 24 sin 36^◦

• 24 tan 36^◦

• 24 cos 36^◦

• sin 36^◦ / 24

• cos 36^◦ / 24

To find length x we should use:

• 17 sin 62^◦

• 17 tan 62^◦

• 17 cos 62^◦

• tan 62^◦ / 17

• sin 62^◦ / 17

The side x is given by:

• 95 tan 46^◦

• 95 / cos 46^◦

• sin 46^◦ / 95

• 95 sin 46^◦

• 95 / sin 46^◦

To find the side x we need to calculate:

• tan 43^◦ / 20

• 20 / tan 43^◦

• 20 tan 43^◦

• 20 cos 43^◦

• 20 sin 43^◦

To find the angle θ we need to use:

• 
• 
• 
• 
• 

The angle θ, correct to one decimal place, is:

• 53.1^◦

• 36.9^◦

• 51.3^◦

• 38.7^◦

• 53.3^◦

The direction shown has the three-figure bearing:

• 030^◦

• 060^◦

• 120^◦

• 210^◦

• 330^◦

The direction shown could be described as the three-figure bearing:

• 030^◦

• 060^◦

• 120^◦

• 210^◦

• −030^◦

Correct to one decimal place, angle C in this triangle equals:

• 34.8^◦

• 46.3^◦

• 53.9^◦

• 55.2^◦

• 86.1^◦
