Answer:
The correct option is Plane A because it was 27.43 miles away ....
Step-by-step explanation:
Angle of elevation of plane A=41 °
Angle of elevation of plane B=43°
height of planes=18 miles
let Δabc be the right triangle formed by the plane A and Δabd be the right triangle formed by the plane B
then ab=18miles
∠c, angle of elevation of plane A=41 °
then distance bc=?
sinc=ab/bc
sin(41°)=18/bc
bc=18/0.65
bc=27.437 miles
Now
∠d, angle of elevation of plane B=43°
then distance bd=?
sinc=ab/bd
sin(43°)=18/bd
bd=18/0.68199
bd=26.393 miles
As bc>bd
The correct option is Plane A because it was 27.43 miles away ....
7 1\5=7x5+1=36\5
36\5 x 100=720%
The <em>correct answer</em> is:
Use the circumcenter to determine the center of the circle
.
Explanation:
The steps James has completed have constructed the perpendicular bisectors of two sides of the triangle, DE and EF. The point where the perpendicular bisectors of the sides of a triangle meet is the circumcenter of the triangle. This is also the center of the circumcircle, or circumscribed circle.
We need to extend these bisectors so that they intersect. We then set our compass on this point and set the width from this center to any vertex of the triangle. This will be the radius of the triangle; we draw the circle and are finished.
