Answer:
x value would be 2
Step-by-step explanation:
The computation is shown below:
Given that
x^2 + 2x = 8
x^2 + 2x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) - 2(x + 4) = 0
(x - 2) (x + 4) = 0
So, x value would be 2
x - 2 = 0
x = 2

Actually Welcome to the Concept of the Quadrilaterals.
Basically we know that, the sum of opposite angles of a quadrilateral inscribed in a circle is always 180°.
so applying this law here, we get as,
2X + (3X-10) = 180°
=> 5X - 10° = 180°
=> 5X = 190°
=> X = 190°/5
=> X = 38°
thus the angle X= 38°.
13 is the answer if I'm correct
The answer would be *A 6.30inches*
