**Draw the triangle **

**Hence we have A+B+C = 180**

**50+80+C = 180**

**130+C = 180**

**C = 180 - 130**

**C = 50**

**(i)**

**The bearing of B from C = 90 - 50 = 40°**

**(ii) **

**Bearing of A from B**

**90+50(alternate angle to A) **

**= 140°**

**(iii) **

**Distance between B and C**

**Using sine rule **

**C/sinC = a/SinA**

**40/sin50 = a/sin50**

**Cross multiply **

**asin50 = 40sin50**

**a = 40km**

**Hence distance between B and C = 40km**

**(iv) **

**Using cosine rule **

**b²= a²+c² - 2acCosB**

**where a = 40, c= 40 and B=80**

**b² = 40²+40² -2*40*40cos80**

**b² = 1600+1600 - 3200(0.1736)**

**b² = 3200 - 555.52**

**b² = 2644.48**

**b = âˆš2644.48**

**b = 51.42km**

**(v)**

**Height of Î”ABC**

**Draw the triangle **

**Area of the triangle **

**=1/2acSinB**

**=1/2*40*40sin80**

**=800(0.9848)**

**=787.84km²**

**Hence 1/2bh=787.84**

**bh=2*787.84**

**h=2*787.84/b**

**h=2*787.84/51.42**
