Find the missing values of the variables. The diagram is not to scale. 125°
yº
124/xº
65°
a. x = 124, y
= 125
b. x 56, y 114
C. X =
114, y = 56
d. X =
56,y
= 124
e. X = 56,y
= 125

b. x = 56; y = 114

Step-by-step explanation:

✅124° + x° = 180° (linear pair/angles on a straight line)

Subtract 124° from each side

124° + x - 124° = 180° - 124°

x = 56°

✅x + y + 125° + 65° = 360° (sum of interior angles of a quadrilateral)

plug in the value of x

56 + y + 125 + 65 = 360

246 + y = 360

Subtract 246 from each side

246 + y - 246 = 360 - 246

y = 114°

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
