A bridge over a river has the shape of a circular arc. The span of the bridge is 24 meters. (The span is the length of the chord
kompoz [17]

Answer:

20 meters

Step-by-step explanation:

Seeing the image attached, we can observe that there is a triangle formed by half of the chord of the arc, the radius (hypotenusa) and part of the radius (r-4). Using pythagoras theorem in this triangle, we have:

(r-4)^2 + 12^2 = r^2

r^2 - 8r + 16 + 144 = r^2

8r = 160

r = 20

So the radius of the circle that contains this arc is 20 meters.

yuradex [85]

Step-by-step explanation:

-2x-5=5x + 6

-2x - 5x = 6 + 5

-7x = 11

x = -11/7

x = 1.571

y = 5(1.571) + 6

y = 7.855 + 6

y = 13.855
