<span>The answer to this item is the first choice, radius. The line formed by the radius to the chord of the circle which forms a right angle with the chord is also the perpendicular bisector of the chord. The answer therefore to thisi tem is the first choice, radius. </span>
Answer:
523.8 miles
Step-by-step explanation:
The drawing attached represents the question. We create a triangle with the distances from each pair of cities, and we call the distance from B to C by 'd'.
First, we need to find the angle BAC:
55° + BAC + 7° = 90°
BAC = 28°
Then, we can use the law of cosines to find the value of d:
d^2 = 470^2 + 890^2 - 2*470*890*cos(BAC)
d^2 = 470^2 + 890^2 - 2*470*890*0.8829
d^2 = 274365.86
d = 523.8 miles
Answer:
x=37
Step-by-step explanation:
4x-2=3x+35 Add 2 to both sides.
<u>+2 +2</u>
4x=3x+37 Subtract 3x on both sides.
<u>-3x -3x</u>
x=37
I hope this helps!! Have a great day ^^
