<h3>
Answer: B. 26</h3>
============================================
Use law of cosines to find angle A
a^2 = b^2 + c^2 - 2*b*c*cos(A)
9^2 = 6^2 + 14^2 - 2*6*14*cos(A)
81 = 36 + 196 - 168*cos(A)
81 = 232 - 168*cos(A)
81 - 232 = -168*cos(A)
-151 = -168*cos(A)
-168*cos(A) = -151
cos(A) = (-151)/(-168)
cos(A) = 0.8988095
A = arccos(0.8988095)
A = 25.9979801
A = 26 degrees approximately
Point S reflected over the y axis would be (9,0)
Answer:

Step-by-step explanation:
Given:
The given AP is.
12,0,-12,......

The first term of an AP 
Common difference 
We use the the formula for nth term of an AP.
for 87th term





Therefore, The 87th term of given series is -1020.
Direct proportionality formula:
y = kx
where: y varies directly on x by k, the constant of proportionality;
In this problem, we substiture k with p.
y = total earning
p = hourly rate
x = no. of hours worked
y = 108
p = ?
x = 12 hrs
y = px
108 = p(12)
108/12 = p(12)/12
p = 9 hourly rate or rate per hour.
p = y/x
p = $108 / 12hrs
Congruence transformation results to a perimeter of any polygon that is the same as the original dimensions and shape. In this case, this is similar to translation where all dimensions, angles are retained constant. The answer to this problem hence is B
