Answer:
x = 7
Step-by-step explanation:
From figure:
⇒ ∠DOC = ∠BOA
Since the diagonals of a trapezium divide each other proportionality.
AO/OC = BO/OD
⇒ (x + 5)/(x + 3) = (x - 1)/(X - 2)
⇒ (x - 2)(x + 5) = (x - 1)(x + 3)
=> x² + 5x - 2x - 10 = x² + 3x - x - 3
⇒ x² + 3x - 10 = x² + 2x - 3
⇒ x² + 3x - 10 - x² - 2x + 3 = 0
⇒ x - 7 = 0
⇒ x = 7
Therefore, the value of x = 7.
Hope it helps!

Answer:
7
Step-by-step explanation:
AO/OC = BO/OD
(x + 5)/(x + 3) = (x - 1)/(X - 2)
(x - 2)(x + 5) = (x - 1)(x + 3)
x² + 5x - 2x - 10 = x² + 3x - x - 3
x² + 3x - 10 = x² + 2x - 3
x² + 3x - 10 - x² - 2x + 3 = 0
x - 7 = 0
x = 7
