Question

The perimeter of the scalene triangle is 54.6 cm. A scalene triangle where all sides are different lengths. The base of the triangle, labeled 3 a, is three times that of the shortest side, a. The other side is labeled b. Which equation can be used to find the value of b if side a measures 8.7 cm?

Answer 1

Step-by-step explanation:

we know that

the perimeter of a triangle is equal to

P=a+b+cP=54.6cmP=a+b+cP=54.6cm equation 1

P=a+b+cP=8.7+26.1+bP=a+b+cP=8.7+26.1+b equation 2

equate equation 1 and equation 2

54.6=(8.7+26.1)+b54.6=34.8+b54.6=(8.7+26.1)+b54.6=34.8+b

therefore

34.8+b=54.6

Answer 2

Answer: C. 34.8+b=54.6
