I can help you but i cant see with the reflection thingy
Answer: 6
Step-by-step explanation:
They are similar triangles so they have proportionality
For the small triangle the side is 2 and the hypoteneuse is 4, for the large triangle the side is 5 so the entire hypoteneuse is 10. 10-4 = 6 which is the missing side
-25 15/19 + 9/1
get a common denominator of 19
they multiplied 9/1 * 19/19 = 171/19
-25 15/19 + 171/19 =
change the mixed number to an improper fraction
(19* 25 +15)/19 = 490/19
-490/19 + 171/19 =
add together
-319/19
now convert the improper fraction back to a mixed number
19* 16 =304 319-304=15
-319/19 =-16 15/19
