Answer:
1 dollar is equal to 0.75 E
Step-by-step explanation:
120$ = 90 e -----> 4$ = 3E
250$ = 187.50 e -----> 4$ = 3E
400$ = 300 e -----> 4$ = 3E
----------------------------------
from this we know 4$ = 3E
1 E = 4$/3
1 E = 1.33...$
---------------------
1 $ = 3/4 E
1 $ = 0.75 E
---------------------
1.33...$ dollars is equal to 1 E and
1 $ is equal to 0.75 E
-----------------------------------
90 x 1.33... =120
187.50x1.33...= 250
300 x 1.33... = 400
--------------------------

Supplementary angles add up to 180, so
6x+60+90 = 180 and solve for x
6x= 30
x=5
