Answer:

B) 60

Step-by-step explanation:

<u>Given:</u>

<A = 2x
<B = 60
<A and <B are supplementary angles (they add up to 180)

<u>Equation:</u>

<A + <B = 180

2x + 60 = 180

2x = 180 - 60

2x = 120

x = 60

A ball rolled from Point A to Point B in 18 second at a speed of 14 m/s. IT took another 18 seconds to roll form Pint B to Pint

vaieri [72.5K]

Answer:

d=252m, u dint put the speed it was rolling at from point B to C so I could only solve for A to B. However if you use the formula below you can find the distance from B to C and add that to A to B giving the total distance rolled.

Step-by-step explanation:

d=vt

v=14m/s

t=18s

d= vt, (14m/s)(18s)

d=252m
