Answer:

(a).\ Two\ triangles\ are\ similar\\\\(b).\ Width\ of\ river\approx 145.5\ ft

Step-by-step explanation:

(a): <u><em>Similar Triangles(AA):</em></u> If two angles of a triangle is equal to corresponding two angles of other triangle. The two triangles are similar.

In\ the\ \triangle ABC\ and\ \triangle EDC\\\\\angle DCE=\angle BCA\ \ \ \ \ (opposite\ angles)\\\\\angle CDE=\angle CBA\ \ \ \ \ (Right\ angles)\\\\Hence\ By\ AA\ Theorem\ These\ two\ triangles\ are\ similar

(b):

\triangle ABC\ and\ \triangle EDC\ are\ similar\\\\\frac{AB}{DE}=\frac{BC}{CD}\\\\BC=100\ ft,\ CD=22\ ft,\ DE=32\ ft\\\\\frac{AB}{32}=\frac{100}{22}\\\\AB=\frac{100}{22}\times 32\ \ \ \ \ \ \ \ Multiplying\ both\ sides\ by\ 32\\\\AB=\frac{3200}{22}\\\\AB=145.45\ ft\approx 145.5\ ft

A rectangular vegetable patch has a perimeter of 36 meters and an area of 80 square meters. What are the dimensions of the veget
hjlf

Answer: 5 and 4

Step-by-step explanation:

Perimeter = 2 ( L + W)

18 = 2(L + W) divide through by 2

9 = L + W

9 - L = W

Area = L * W

20 = L (9 - L)

20 = 9L - L^2

L^2 - 9L + 20 = 0 factor

(L - 5) (L - 4) = 0

Set both factors to 0 and solve for L

L = 5 and L = 4
