Answer:
Step-by-step explanation:
130+5x=180
130-130+5x=180-130
5x=50
x=10
Value of x = 10 to make ABCD a parallelogram.
" Parallelogram is a quadrilateral in which opposite sides are parallel and congruent to each other."
Formula used
∠A +∠B +∠C + ∠D = 360°
According to the question,
∠B = ∠D = 130°
∠C = 5x
To make ABCD a parallelogram,
∠C= ∠A = 5x
Substitute the value in the formula
5x +130 +5x + 130 =360
⇒10x + 260 = 360
⇒x = 10
Hence, Value of x = 10 to make ABCD a parallelogram.
