Isosceles trapezoid , diagonals are equal
AC = DB
x + 1 = 2x - 3
x = 4
So AC = DB = 4 + 1 = 5
Answer:
The length of the diagonals = 5
Mes angle P = mes arc (ORQ) / 2
mes angle R = mes arc(OPQ) / 2
But mes arc(OPQ+ORQ) = 360° & ===> mes angle (P+R) =arc(OPQ+ORQ) /2
= 180°. Then P+R =180°.
Replace P & R by their respective values: y°+3y°+8°=180°
4y° = 172° ===> y°=43°
To get the answer, multiple 20 by 0.45= $9 than subtract 9$ from $10 which equals $1.
Use the data given below to answer the following questions 68,63,67,66,65,87,69,61,86,82,28, a. What is the outlier of the data?
Lady_Fox [76]
The outlier is 28 because there is a big gap between 28 and 61
to find the mean add all the numbers together then
divide the number of values added
