Answer:
middle brother = x
older brother = x+1
younger brother = x-1
x-1+x+x+1=129
3x+0=129
3x=129
x = 43(middle brother)
43-1 = 42(younger brother)
43+1 = 44(elder brother)
Check:
43-1+43+43+1=129
42+43+44=129
129=129
Answer:
42.08inches
Step-by-step explanation:
Given data
SIze of TV= 50 inch
Width= 27inches
Length= ??
Applying Pythagoras theorem
z^2= x^2+y^2
50^2= x^2+27^2
square root both sides
50^2= x^2+27^2
2500= x^2+ 729
2500-729=x^2
1771=x^2
x= √1771
x= 42.08
Hence the lenght is 42.08inches
