There are 5 red balls,4 blue balls and n green balls inside a bag. a ball is taken from the bag at random. given that the probability of picking a green ball is 0.4,find thr value of n.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
