Answer:
28
Step-by-step explanation:
It helps to plot the points on a graph. It is easy to see that three of the sides are of length 6, and the remaining two are the hypotenuse of a 3-4-5 triangle, hence length 5.
3×6 +2×5 = 28
The perimeter of this polygon is 28 units.
The measure of angle A is 65°
Explanation:
Given that ABCD is a quadrilateral inscribed in a circle.
The measure of angle A is
The measure of angle B is
The measure of angle D is
We need to determine the measure of angle A.
Since, we know that the angles B and D are opposite angles and the opposite angles of a quadrilateral add up to 180°
Thus, we have,
Substituting the values, we have,
Thus, the value of x is 32°
Substituting the value of x in the measure of angle A, we get,
Thus, the measure of angle A is 65°
