All triangles inner angles addition equals to 180°
So if you’re finding the x° then minus the other angles from 180°
23°+129°+x=180°
x=180°-129°-23°
x=28° 
I hope this helped :)

The ratio is 0.302 (30.2%)
Step-by-step explanation:
In this problem, we have:
P = 222 million is the total number of people in the country
p = 67 million is the number of people which are under 20
Here we want to find the ratio of people that are under 20 with respect to the total population. Therefore, we have to calculate the ratio

Plugging in the numbers, we find:

We can also write it in percentage,
