The arcs FA, AB, and <u>BF</u> make up the entire circle, so their measures sum to 360°:

arcFA + arcAB + arcBF = 360°   →   arcBF = 360° - 160° - 140° = 60°

By the inscribed angle theorem, angle BAF has measure equal to half of that of arc BF, so

angleBAF = 30°

By the secant-tangent theorem (not sure if there's an official name for it), the measure of angle ACF is equal to half the difference of the arcs it intercepts, namely BF and FA, so that

angleACF = 1/2 (arcFA - arcBF) = 1/2 (160° - 60°) = 50°

Now use the law of sines for solve for FA:

sin(angleACF) / FA = sin(angleBAF) / FC

sin(50°) / FA = sin(30°) / 10

FA = 10 sin(50°) / sin(30°) ≈ 15.3

What is the best description of the acceleration of an object?
shtirl [24]

Answer:

A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.

Step-by-step explanation:

By definition, Acceleration is the rate of change of Velocity of an object.

I.e it is the( final velocity minus initial velocity ) ÷  by the time it took for the velocity to change.

If we observe the choices only one choice gives us all 3 components (final velocity, initial velocity, time taken for velocity to change), which is :

A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
