Carrie and Alex are playing hide and seek Alex stands at the house to count Carrie runs 25 m west and finds nowhere to hide. She Continues 60 m north to the tree

Step-by-step explanation:

Since we are not asked what to find, we can as well calculate the displacement of Carrie.

Displacement will be gotten using Pythagoras theorem;

Given

direction through west x = -25m

direction through north y = 60m

Required

Displacement d

According to the theorem;

d² = x²+y²

d² = (-25)²+(60)²

d² = 625 + 3600

d² = 4225

d = √4225

d = 65 m

Hence the displacement of Carrie is 65m

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
