Factor out the cos<span>θ:
</span>cosθ (2sin<span>θ + sqrt3) = 0
</span>Therefore, the only ways this can happen are if either cosθ = 0 or if (2sin<span>θ + sqrt3) = 0
</span>The first case, cosθ = 0 only at θ <span>= pi/2, 3pi/2.
</span>The second case, <span>(2sin<span>θ + sqrt3) = 0 simplifies to:
</span></span>sin<span>θ = (-sqrt3)/2
</span><span><span>θ = 4pi/3, 5pi/3
</span></span><span><span>Therefore the answer is A.

Answer:
The distance from the house to the school is equal to 
Step-by-step explanation:
Let
A-----> the distance from house to the park
B----> the distance from the park to the school
C----> the distance from house to the school
so

we know that


so
Find the the value of C


therefore
The distance from the house to the school is equal to 
Answer:
Step-by-step explanation:
12:3 = 12 divide by 3 = 4
3 divide by 3 = 1
Im pretty sure it would be 48 since the beginning number is 50 and A is 2 more down. and if 1 mark = 1 unit then i think it will be 48
