The perimeter of the scalene triangle is 54.6 cm.




Which equation can be used to find the value of b if side a measures 8.7 cm?


8.7 + b = 54.6

17.4 + b = 54.6

26.1 + b = 54.6

34.8 + b = 54.6

the correct question is
The perimeter of the scalene triangle is \(54.6\) cm.
Which equation can be used to find the value of b if side a measure \(8.7\) cm and side c measure \(26.1\) cm?

we know that
the perimeter of a triangle is equal to

\(P=a+b+c \\ P=54.6 cm\) equation 1

\(P=a+b+c \\ P=8.7+26.1+b\) equation 2

equate equation 1 and equation 2
\(54.6=(8.7+26.1)+b \\ 54.6=34.8+b\)

therefore

the answer is the option D
\(34.8 + b = 54.6\)

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
