Answer:
25
Step-by-step explanation:
10 / 2 = 5 x 5 = 25
-5,0 and-200 cannot represent the area of polygon
As 0 has no value and there are impossible to make a polygon with negative value
2. 225
4. 25/36
6. 0.001
8. 8-20=-12
10. 34-16=18
12. 15/5=3^3=27
14. ?? confused...
16. 8
18. 11.5+4=15.5
20. 3(225)+10=675+10=685
Answer:
72 degrees.
Step-by-step explanation:
If the angle is x degrees its complement is 90-x degrees and it's supplement is 180-x degrees.
4(90-x) = 2/3(180 - x)
360 - 4x = 120 - 2/3 x
360 - 120 = -2/3 x + 4x
240 = -2/3 + 12/3 x
240 = 10/3 x
x = 240 * 3/10
x = 72 degrees.
