The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28

Answer:
x = 36 and y = 72
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an external angle to the triangle on the right, thus
y = 2x
The sum of the 3 angles in a triangle = 180
Consider the triangle on the left. then
x + 2y = 180 ← substitute y = 2x
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36 and y = 2x = 2 × 36 = 72
I'm not completely sure, but this should be exponential growth.
If so, the equation for exponential growth is: y = a(1 + r)^t
If I substitute them with the information you gave me, then is would look like this:
y = 281.4(1 + 0.02)^t
**t = is the number of years after 2000 (based on your question)**

Step-by-step explanation:
let the percent of found balloons be x
given,
total number of balloons= 70
number of found balloons= 28
according to the question,
x% of 70= 28
x/100 × 70 = 28
x=40
hence 40% of the balloons were found
