Answer:
Step-by-step explanation:
let the first angle be 5x
second be 4x
and third be 1x
as we know that by adding all the sides of triangle we get 180°
therefore ,
5x+4x+1x=180°
10x=180°
hence ,
x=18°
first angle - 18*5 = 90°
second angle - 18*4=72°
third angle - 18°
HOPE THIS HELPS YOU !!!
Answer: 45
Step-by-step explanation:
I would go with B but this is a tricky question. Hopefully i am correct.
72 what in inches? please clarify
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
