From the diagram we see there is a 90 degree angle, also the radius from a point B to the center of the circle is the same as the radius from the center of the circle to the right angle.
Let the radius be r.
sin a=opposite/adjacent
sin 76.6=r/(r+112)
0.973(r+112)=r
0.973r+108.976=r
r-0.973r=108.976
0.027r=108.976
r=108.976/0.027
r=4036.15 miles
the radius of earth will r=4036.15 miles
Answer:
y=-1.5
X=1.75
Step-by-step explanation:
Yuh arrange the equations in order for easy subtracting of the equations.
-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.
6x+3y=6
3y=-6x+6 then divide both sides by three to get y
y=-2x+2
now arrange
y=-2x+2
y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x
Answer:
$160.16
Step-by-step explanation:
Multiply $143 and 12%
Make 12% as decimal: 0.12
143*0.12
$160.16
I believe the GCF would be 2n
