Given EF is the midsegment of Isosceles trapezoid ABCD. BC = 17x, EF = 22.5x + 9 and AD = 30x + 12, find BC.
User: Given kite WXYZ. The measure of angle WXY = 86 and the measure of angle WZY = 22. Find the measure of angle ZWX.
**Weegy:** angle ZWX = [360 - (86 + 22)]/2
= 126 **User:** Given kite ABCD. EB = 2x + 4 and BD = 5x + 1. Find EB.
**Weegy:** If ED is measuring across the long diagonal, then EB = ½BD
2x+ 4 = ½(5x+1)
2x+ 4= 2.5x + .5
3.5 = .5x
7 = x **User:** A trapezoid has one pair of congruent sides.
always, sometimes, never **Weegy:** A trapezoid has exactly one pair of PARALLEL sides, and an isosceles trapezoid has exactly one pair of congruent sides as well. So, if you are talking about a trapezoid (but not necessarily an isosceles one), the answer is sometimes. **User:** Given rectangle WXYZ. If WX = 10y + 4 and YZ = 13y - 8, find the value of y. **Weegy:** WX = YZ
10y + 4 = 13y - 8 (add 8 to both sides)
10y + 12 = 13y (subtract 10y from both sides)
12 = 3y (divide both sides by 3)
4 = y (More)

Find the circumference and area of a circle with radius of 3 feet. Use pi = 3.14 and round your answers to the hundredth **Weegy:** C = 2 pi R = 18.85 feet (pi = 3.14159).
A = pi R^2 = 3.14159 x (3) x (3) = 28.27 sq ft.

Segments AB and CB are tangents to Circle O. AC = 8 units, AB = 4x + 8 and
CB = 7x - 13. Find the perimeter of triangle ABC.
**Weegy:** Is AB = 4x + 8 units? (not the equation of the line is y = 4x + 8?)
If so then ABC is an isosceles triangle so AB = BC
4x +8 = 7x - 13
21 = 3x
x = 7, AB = CB = 36
Perimeter = 36+36+8 = 80

User: What is the angle of rotation (in degrees) of a regular decagon?
**Weegy:** What is your question for weegy today? **User:** What is the angle of rotation (in degrees) of a regular decagon?
**Weegy:** 60 degrees. Since a regular hexagon's sides are evenly distributed, you can just take the total 360 degrees and divide by 6 to give you 60 **User:** thank you **Weegy:** No problem. Thank you for using weegy. Have a good day. Do you have another question? (More)
