Answer:
Option 1 is correct. Measure of XWZ is 248°
Step-by-step explanation:
Please see the attachment for figure.
XY and YZ tangent of circle with centre O.
XY makes central
We need to find measure of XWZ
It would be major angle of XY arc.
As we know the sum of minor and major arc at centre would be 360°
Option 1 is correct.
Thus, Measure of XWZ is 248°
<u>Given</u>:
Given that the graph of a triangle BDE.
The coordinates of the triangle are B(-2,3), D(2,6) and E(3,2)
We need to determine the perimeter of the triangle BDE.
<u>Length of BD:</u>
The length of BD can be determined by substituting the coordinates (-2,3) and (2,6) in the formula,
<u>Length of DE:</u>
Substituting the coordinates of D(2,6) and E(3,2) in the formula, we get;
<u>Length of BE:</u>
Substituting the coordinates of B(-2,3) and E(3,2) in the formula, we get;
<u>Perimeter of ΔBDE:</u>
The perimeter of triangle BDE can be determined by adding the lengths of BD, DE and BE.
Thus, we have;
Hence, the perimeter of ΔBDE is √17 + √26 + 5
Thus, Option A is the correct answer.
