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°
X+y is 180-95 because all triangles add up to 180.
And X and Y must be equel bc AB is a perpendicular bisector(this means it cuts the angle in equel half’s)
So 180-95/2 is 42.5
Answer:
x = -6
Step-by-step explanation:
-7x+16=58
Subtract 16 from each side
-7x+16-16=58-16
-7x = 42
Divide by -7
-7x/-7 = 42/-7
x = -6
Step-by-step explanation:
1. if to evaluate the given experssion, then
7⁶(7²-7+1)=7⁶*43.
2. if to divide this evaluated expression by 43, then
7⁶*43/43=7⁶.
