To re-phrase this: 50 is a certain percent of 90.
this can be written mathematically as 50=x%*90
let's divide both sides by 10:
5=x%*9
and divide both sides by 9:

which in decimals is approximately 0.56 (but not exactly).
so 0.56=x%
and the x then 56
so 50 is
approximately 56% of 90:
exactly 56%of 90 is 50.4
I think that the answers are 4, 4 and 25 respectively

Answer:
3 (z = 35)
Step-by-step explanation:
(22 + 19) + 104 + z = 180° => triangle sum theorem
41 + 104 + z = 180
145 + z = 180
145 + z - 145 = 180 - 145
z = 35
140 kilometers, but if you want miles it will be 86.992 miles.
