I need help on a question. Could someone help me?

32

Step-by-step explanation:

The total sum of the degrees in a triangle is 180, so, if we subtract 116 from 180, we get 64. Since there are still 2 corners left, we divide 64 by 2 and get 32. So, x =32

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

yes. we do proportions in probabilities.
