68. add the two measures then subtract from 180.
Answer:
x=0.69897009
Step-by-step explanation:
expand by logarithms
10^x=5
=log(10^x)=log(5)
=x log(10)=log (5)
log base 10 of 10 is 1
x.l =log(5)
multiple bothside by 1
x=log(5)
x=0.6989709
Three plus a number times two.
X+x+1+x+2=57
3x+3=57
3x=54
x= 54/3
x= 18
x+1= 19
x+2= 20
Therefore 20 is the largest
