Sum of inside angles of a polygon= 180º(n-2)
n=number of sides.
This polygon has 6 sides, the sum of all its angles would be=180º(6-2)=720
let´s:
xº=inside angle
xº=720º-sum of the others inside angles.
xº=720º-(75º+130º+120º+105º+145º)=720º-575º=145º
yº=180º-xº=180º-145º=35º
Answer: yº=35º
for every member to get a shirt you would need to order 9 packages of shirt (because 5 times 9 is 45) and for caps the minimum to order would be 15 packages of caps
explanation
caps=3 per package
shirts=5 per package
divide 45 by and get 15
15 is the total packages of hats needed to order
for shirt 45 divided by 5 is 9
9 is the total packages of shirts needed to order
Answer:
17:3
Step-by-step explanation:
Hope this helps!
The answer is 10 because 2 goes into 20 10 times.
