In the figure, ∆ABC~∆XYZ. What is the perimeter of ∆ABC? Show your work.
Elina [12.6K]

Answer:

49 units

Step-by-step explanation:

Given the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{BC}{YZ} = \frac{AB}{XY}, substitute values

\frac{BC}{44} = \frac{11}{22} ( cross- multiply )

22BC = 484 ( divide both sides by 22 )

BC = 22

------------------------------------------------

Similarly

\frac{AC}{XZ} = \frac{AB}{XY}, substitute values

\frac{AC}{32} = \frac{11}{22} ( cross- multiply )

22AC = 352 ( divide both sides by 22 )

AC = 16

Thus perimeter of Δ ABC is

perimeter = AB + BC + AC = 11 + 22 + 16 = 49 units

Lelu [443]

Answer:

$378

Step-by-step explanation:

Full price:  1.00($450) = $450

20% off:     0.20($450) = $90

Sale price (after 20% off):  (1.00 - 0.20)($450) = 0.80($450) = $360

Final price, including tax:  (1.00 + 0.05)($360) = $378
