If triangle tsr is congruent to triangle tfe how do i find the perimeter of triangle tfe

72.5

Step-by-step explanation:

To find the perimeter of the triangle, add all three sides. Since triangles TSR and TFE are similar, the missing side of TFE can be found using proportions.

Solve by cross multiplying:

40(x) = 25(22)

40x = 550

x = 13.75

Find the other side by repeating the process.

Solve by cross multiplying:

40(y) = 25(54)

40y = 1350

x = 33.75

The perimeter is 25 + 13.75 + 33.75 = 72.5

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05
