Answer: B
. on your test
Step-by-step explanation:
It’s A (y=6.2x)
This is just me writing so that it’s 20 characters long
We plug in d as 2, so 8/4 - d would be 8/4 - 2. Now, 8/4 is equal to 2, so 2 - 2 = 0.

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
