Answer:

θ=0,π/3,π,5π/3,2π

Step-by-step explanation:

cosθ sinθ-1/2 sinθ=0

sinθ(cos θ-1/2)=0

Either sin θ=0

θ=0,π,2π

cosθ-1/2=0

cos θ=1/2=cos π/3,cos(2π-π/3)

θ=π/3,5π/3

Based on the picture..Find the area in terms of xFind the perimeter in terms of x

Vlad1618 [11]

The area of a rectangle is given by the product of its dimensions.

If this rectangle has a length of 2x + 7 and a width of x + 4, its area is:

$\begin{gathered} \text{Area}=\text{length}\cdot\text{width} \\ \text{Area}=(2x+7)(x+4)_{} \\ \text{Area}=2x^2+8x+7x+28 \\ \text{Area}=2x^2+15x+28 \end{gathered}$

The perimeter is the sum of all side lengths, so we have:

$\begin{gathered} \text{Perimeter}=(2x+7)+(x+4)+(2x+7)+(x+4) \\ \text{Perimeter}=6x+22 \end{gathered}$
