Answer:
1. 91
2. 75
3. 90
4. 94
5. 48
6. 60
7. yes!
8. no, the first angle should be 39.5
9. no, the first angle should be 28.67
10. no, the first angle should be 31.75
11. 67.5 (for both angles)
12. 60 (for both angles)
13. 24 (for both angles)
14. the side with the equation is 17, while the x is 73
15. (this might be wrong but) 10x + 2x + 168 =180
16.every triangle has atleast two acute angles because then the angles would be greater than 180.
17.
a= 72
b= i believe it is limited, because each card is probably around the same shape and size, so, then the value of z would be pretty much the same, unless you put the cards in a different structure unlike how it's shown.
Step-by-step explanation:
i put the pictures just in case you wanna know how to do it, but the work is pretty scattered since i tried to answer all of this as fast as i could lol
