A plane is flying at an altitude of 5km. From the plane, the angle of depression to airport A and airport B are 45 and 31 degrees respectively. a) using a scale of 1cm rep 4km, draw a scale. b) determine the distance between the two airports.

True bearing huonyeshwa kwa namba tatu na hupimwa kuanzia Kaskazini (North) kwa mwelekeo wa saa.
True bearing ya q kutoka T imetolewa kama $100^\circ$.

Compass bearing (au quadrantal bearing) hupimwa kutoka Kaskazini (N) au Kusini (S) kuelekea Mashariki (E) au Magharibi (W).
Kwa true bearing ya $100^\circ$:

• Hii iko katika roboduara ya pili (kati ya $90^\circ$ na $180^\circ$), ambayo ni Kusini-Mashariki.
• Ili kupata angle ya compass bearing, tunatoa true bearing kutoka $180^\circ$.

Kwa hivyo, compass bearing ni S $80^\circ$ E.

Swali tayari limetoa true bearing ya q kutoka T.
True bearing ni $100^\circ$.

a) Compass bearing q kutoka T: $\boxed{\text{S } 80^\circ \text{ E}}$

b) True bearing ya q kutoka T: $\boxed{100^\circ}$
