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?

4(8.7) + b = 54.6.

b = 19.8 cm.

Step-by-step explanation:

The sum of the sides = the perimeter = 3a + a + b = 54.6.

Now a = 8.7, so:

3(8.7) + 8.7 + b = 54.6

4(8.7) + b = 54.6.

b = 54.6 - 4(8.7)

b = 19.8.

step-by-step explanation:

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
