Let d = # digital cameras
Let m = # manual cameras
d + m = 240 equation 1
(d-82) = 3(m-26) equation 2
d - 82 = 3m - 78
d - 3m = 82 - 78
d - 3m = 16 equation 2 simplified
We have two equations with 2 unknowns:
d + m = 240
d - 3m = 16 subtract equation 1 from equation 2
---------------
-4m = -224
m = -224/-4
m = 56
d + m = 240
d = 240-m
d = 240-56
d = 184
He started with 184 digital cameras and 56 manual cameras

Step-by-step explanation:
Answer:
the missing side is a square root of 1475 or if you want a more rounded answer then it would be 38.4
Step-by-step explanation:
Use the Pythagorean theorem a2+b2=c2
17 squared + b2 = 42 squared
289+b2=1764
subtract 1764 and 289 =
