Answer:
1. BC = 86 Km
2. 090°
Step-by-step explanation:
1. Determination of BC
AB = 27 Km
AC = 82 Km
BC =?
Since the figure is a right angle triangle, we shall determine BC by using pythagoras theory. This is illustrated below:
BC² = AB² + AC²
BC² = 27² + 82²
BC² = 729 + 6724
BC² = 7453
Take the square root of both side
BC = √7453
BC = 86 Km
2. Determination of the bearing of C from A.
From the diagram given above, we can see that angle from A and C is 90°. Thus, the bearing of C from A is 090°
P(A/B) = P(A∩B) / P(B)
P(A/B) = (3/10) / (2/5) = 3/10 x 5/2 = 15/20 = 3/4
The best estimate is probably 40.
Because 280 / 7 = 40.
Answer:
Step-by-step explanation:
(1 - i) / (sqrt(3 + 4i)
= (1 - i) /
