Answer :
the correct question is
The perimeter of the scalene triangle is [tex]54.6[/tex] cm.
Which equation can be used to find the value of b if side a measure [tex]8.7[/tex] cm and side c measure [tex]26.1[/tex] cm?
we know that
the perimeter of a triangle is equal to
[tex]P=a+b+c \\ P=54.6 cm [/tex] equation 1
[tex]P=a+b+c \\ P=8.7+26.1+b[/tex] equation 2
equate equation 1 and equation 2
[tex]54.6=(8.7+26.1)+b \\ 54.6=34.8+b[/tex]
therefore
the answer is the option D
[tex]34.8 + b = 54.6[/tex]

Answer:The correct answer is :
34.8 + b = 54.6
Step-by-step explanation:
The perimeter of the scalene triangle = Sum of length of all sides
Given that perimeter of the scalene triangle = 54.6 cm
a = 8.7 cm , c = 26.1 cm
a + b + c= 54.6 cm
8.7 cm + b + 26.1 cm= 54.6 cm
34.8 cm+b = 54.6 cm
From the given options the correct answer is:
34.8 cm+b = 54.6 cm
