1. a. make a proportion here, of percentage.
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again,
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
Answer:
WZX = 110
y = 19
Step-by-step explanation:
We can create the following equation to solve for y.

Reduce
4y = 76
y = 19
We then plug into 4y + 34 to get angle
WZX = 110
