Answer:
We know that a triangle has angles that equal to 180°
![45 + x + 77 + x + 72 = 180 \\ 194 + 2x = 180 \\ 2x = 180 - 194 \\ 2x = - 14 \\ x = - 7](https://tex.z-dn.net/?f=45%20%2B%20x%20%2B%2077%20%2B%20x%20%2B%2072%20%3D%20180%20%5C%5C%20194%20%2B%202x%20%3D%20180%20%5C%5C%202x%20%3D%20180%20-%20194%20%5C%5C%202x%20%3D%20%20-%2014%20%5C%5C%20x%20%3D%20%20-%207)
A= x+72
=-7+72

Here, number of bulletin board = 1
Artwork = 2/5 th, & math papers = 1/5
So, it would be: 1/5 + 2/5 = 3/5
In short, Your Answer would be 3/5 or 0.60
Hope this helps!
