Answer:
hi
x+102° =180°[ Being cointerior angle]
x=180°-102°
x=78°
Also,
y=102°[ the opposite angle of parallelogram are equal]
z=78°[ the opposite of parallelogram are equal]
Hence, x=78°,y=102° and z=78°
In geometry,
A point represents a point
Two points define a line extended on both sides of the points.
Two points define a ray if it extends on only one side of either of the points.
Three or more than three points define a plane.
Now as far as a wall is considered, it is a flat surface on which we can plot infinite points.
Hence the wall represents a plane.

Answer:
(-138) is the answer.
Step-by-step explanation:
Perfect square numbers between 15 and 25 inclusive are 16 and 25.
Sum of perfect square numbers 16 and 25 = 16 + 25 = 41
Sum of the remaining numbers between 15 and 25 inclusive means sum of the numbers from 17 to 24 plus 15.
Since sum of an arithmetic progression is defined by the expression
![S_{n}=\frac{n}{2}[2a+(n-1)d]](https://tex.z-dn.net/?f=S_%7Bn%7D%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D)
Where n = number of terms
a = first term of the sequence
d = common difference
![S_{8}=\frac{8}{2} [2\times 17+(8-1)\times 1]](https://tex.z-dn.net/?f=S_%7B8%7D%3D%5Cfrac%7B8%7D%7B2%7D%20%5B2%5Ctimes%2017%2B%288-1%29%5Ctimes%201%5D)
= 4(34 + 7)
= 164
Sum of 15 +
= 15 + 164 = 179
Now the difference between 41 and sum of perfect squares between 15 and 25 inclusive = 
= -138
Therefore, answer is (-138).
