ABC represents a race path. Find the total distance of the race. Round your answer to the nearest meter.

Race covers 1911 meters.

Step-by-step explanation:

Triangle ABC represents a race path.

Total distance covered by the race = Perimeter of the triangle ABC

We will apply Sine rule in the given triangle to find the unknown sides.

By Sine rule,

     [Since m∠A = 180° - (85 + 60)° = 35°]

AC =

     = 781.57 meters

AB =

     = 679.44 meters

Perimeter of the triangle = AB + BC + AC

                                         = 679.44 + 450 + 781.57

                                         = 1911.01

                                         ≈ 1911 meters

Therefore, the race covers 1911 meters.

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
