Answer:
The largest angle needed is 
.
Step-by-step explanation:
To determine the larges angle as required, let us apply the cosine rule.
= 
+ 
- 2ab Cos C
Since in triangles, the longest side is opposite to the largest angle, then;
= 
+ 
- 2(8 x 12) Cos θ
225 = 64 + 144 - 192 Cos θ
225 = 208 - 192 Cos θ
192 Cos θ = 208 -225
192 Cos θ = -17
Cos θ = 
Cos θ = -0.08854
θ = 
-0.08854
= 95.07962
θ =
The largest angle needed is .
Answer:
2km
Step-by-step explanation:
Distance = Speed ÷ Time
Distance = 3 ÷ 1.5 (as 1 hour and 30 minutes is an hour and a half)
Distance = 2km
