Answer:
A ≈ 5.6
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
× PQ × PR × sin P
= 0.5 × 5.2 × 2.8 × sin50°
≈ 5.6 ( to 1 dec. place )
For Scott
- He is at 100km 30 degrees
For Spock
- He is at 110km 62 degrees
So The difference between them is just algebraic subtraction of their positions
- 110km 62°-100km 30°
- (110-100)km (62-30)°
- 10km 32° apart
Its a chemical element, and it is surrounded by electrons.
