Answer:
The correct option is c.
Step-by-step explanation:
The figure shows the street and block in a small town.
In the given figure (0,0) represents the home and the black hat represents the magic shop.
From the given figure it is clear that the magic shop have coordinates (3,4).
The point (3,4) is 3 units right and 4 units up from the pointy (0,0). It means to walk from home (0,0) to the magic shop a person needs to walk east three blocks and then walk north four blocks.
Therefore the correct option is c.

Answer:
P = 57°
Step-by-step explanation:
Given the following :
PQ = 17
QR = 15
PR = 14
Using the cosine formula since the length of the three sides are given:
a2 = b2 + c2 – 2bccos(A)
To find P:
QR^2 = PQ^2 + PR^2 – 2(PQ)(PR)cos(P)
15^2 = 17^2 + 14^2 – 2(17)(14)cos(P)
225 = 289 + 196 - 476 cosP
476*CosP = 485 - 225
476*CosP = 260
CosP = 260/476
CosP = 0.5462184
P = Cos^-1(0.5462184)
P = 56.892029
P = 57°
