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°
Answer:
-2 = -3(2) + 4
Step-by-step explanation:
Formula: y = mx + b, m = rise/run
Given: b = 4, rise = -3, run = 1
Sub: y = mx + 4
Find m.
Sub: m = -3/1
Simplify: m = -3
Sub: y = -3x + 4
Solve: -2 = -3(2) + 4
