Answer:19. 17 degrees
20. 49 degrees
Step-by-step explanation:
Because of the postulate 50+?=67
So ?=17
And 20.
94+?=143
So
?=49
(Edit)I though you only meant 19 and 20
21. X=8
22. X=12
23.x=8
24.x=7
Traditional 1/2 * base * height
Heron’s formula (it’s quite lengthy so search it up)
Hope this helped you :)

Answer:
A. the area of the large pond is 16 times the area of the small pond
Step-by-step explanation:
let's say 4 is the radius of the small circle, which means the area is 50.26548
if the large circle is 4 times the small circle, that means it's radius is 16 which means the area is 804.24772
so if you divide the big circle area by the small circle area:
804.24772/50.26548
it gives you 16.00000079577 which is rounded to 16
therefore, the bigger circle is 16 times bigger than the smaller circle
