The x would equal 0 and the y would equal 3
If each bird had two wings, there would be 4016 wings. For each two-winged bird we replace with a four-winged bird, the total number of wings would increase by 2. We need 22 more wings, so 11 two-winged birds need to be replaced by four-winged birds. Thus, there are 1997 two-winged and 11 four winged birds.

Answer:
1. x=70
2. x=70
3. x=60
4. x=40
5. x=10
6. x=6
7. x=12
8. x=9
9. 88
10. 76
Step-by-step explanation:
1. Isosceles triangles have two sides equal to each other. If the unequal side is 40 degrees and there are 180 degrees in a triangle, 180-40=140/2=70 degrees for the other two sides.
2. Same explanation as 1.
3. Equilateral triangles all have the same degrees. If 60 is the degree for one angle, it is the degree for the other two as well.
4. Same explanation as 1.
5. All side length of an equilateral triangle are the same. If the side length of one side is 10, the other two sides are 10 too.
6. Same explanation as 5, but with 6 as the side length.
7. It is an isosceles triangle and two sides are equal. Since one side is 12 and the other side is the second of the equal sides, the side length would be 12
8. Same explanation as 7, but with 9 as the side length.
9. 180-46=134-46(other side length)=88 (remaining side length)
10. 2x+2+2x+2+3x+1=7x+5. 7x+5=180. 180-5=175. 175/7=25. 3(25)+1=76.
Hope this helps!!
The answer is x=7. Since the two angles are corresponding. Then it would be 10x-2=9x+5. The answer would be x=7. Please mark me Brainleist
