Step-by-step explanation:
Value of X :-
P + 130 = 180°. (linear pair)
P = 180 - 130°
P = 50°. (internal angle )
Again,
R + 115° = 180° (linear pair )
R = 180° - 115°
R = 65°
Sum of P and R = X .
Reason :-
The sum of two inner angle is equal to the opposite external angle.
Here , P and R are two internal angle and the X is its external opposite .
Then, value of X. = (50°+65°) = 115°
Value of X is 115° .

Answer:
let p =a
130°+a=180°
a=180°-130°
a=50°
let R=Y
Y=180°-115°
Y=65°
let Q=Z
Z+65°+50°=180°
Z+115°=180°
Z=180°-115°
Z=65°
X+65°=180°
X=180°-65°
X=115°
Answer=[X=115°]
