Find BC please in the picture
tatiyna

B. 25 Km. The measure of BC is 25 km.

The easiest way to solve this problem is using the cosine theorem c = √a²+b²-2ab*cos A.

BC = √AC²+AB²-2(AC)(AB)*cos A

BC = √(21km)²+(14km)²-2(21km)(14km)*cos 89°

BC = √441km²+196km²-588km²*(0.017)

BC =√637km²-10.26km²

BC = √636.74km²

BC = 25.03km ≅ 25

The circumference of a circular garden is 153.86. What is the radius of the garden? use 3.14 for pie and do not round your answe
dimaraw [331]

Answer:

24.5 is the answer. It is not rounded.

Step-by-step explanation:

You have to work backwards on this problem.  153.86 divided by 3.14 = 49.  But 49 is only your diameter, so you have to divide by 2 to get radius.  49/2 = 24.5.

Rate me 5 stars please

Also say thanks
