Answer:
1080 degrees
Step-by-step explanation:
The sum of the interior angles of any polygon is:
Sum = (n - 2) * 180
Where n represents the number of vertices of the polygon
This polygon has 8 vertices so:
(8-2) * 180 = 6*180 = 1080 degrees
Well i am thinking the length could be 24 and thw width cold be 12 remember add all the sides that is your perimeter the area is length times width
The simple interest Trey earns if he makes no additional deposit or withdrawal for a period of 6 years is 600
<h3>How to calculate simple interest?</h3>
= 2/100
= 0.02
Simple interest = principal × rate × time
= 5000 × 0.02 × 6
= 600
Therefore, the simple interest Trey earns if he makes no additional deposit or withdrawal for a period of 6 years is 600

Answer: x = 45
Step-by-step explanation:
Quadrilaterals inscribed in a circle have all four vertices on the circle.
A unique property of these types of quadrilaterals is their angle measures: Opposite angles of inscribed quadrilaterals will always add up to 180 (they are supplementary angles).
As such, the inscribed quadrilateral ABCD has opposite angles at AC and BD. Because the quadrilateral is inscribed, this means that the angles A + C and the angles B + D will equal 180 degrees. We can represent the angles measures for B and D in an equation where B + D = 180:
When x = 45, the angle B is 40 degrees and the angle D is 140 degrees.

0.42x = 63
x = 63/0.42
x = 150
