Answer:
Try 30 degrees
Step-by-step explanation:
Because 60 degrees is half of 30 degrees
We are already given with the function to solve for the area:
<span>A(θ) = 16 sin θ ⋅ (cos θ + 1)
</span>
We simply have to substitute the value of the angle into the function. So,
If <span>θ = 90°,
A(</span>90°) = 16 sin (90°) ( cos (<span>90°) + 1 )
Using the calculator or the definition of trigonometric functions at angle of </span><span>90°, we get the value of the area:
</span>A(<span>90°) = 16 square inches</span>

Answer:
The perimeter can be found by calculating lengths of sides using distance formula and then adding up the lengths
Step-by-step explanation:
If the vertices of a quadrilateral are known in the coordinate plane, the vertices can be used to determine the lengths of sides of quadrilateral. The distance formula is used for calculating the distance between two vertices which is the length of the side

after calculating all the lengths of four sides using their vertices, they can be summed up to find the perimeter ..
