Answer: A) Hypotenuse-Leg

This abbreviates to HL

==============================================

Explanation:

Triangle BEC is a right triangle due to the square angle marker at angle E. This is a 90 degree angle. The side opposite the 90 degree angle is always the longest side of the right triangle, aka the hypotenuse. For triangle BEC, that is side BC. Note the tickmark here.

There's a similar tickmark on side DC, which is also a hypotenuse, but for triangle DEC. The tickmarks indicate BC = DC are congruent hypotenuse lengths. That forms the "H" in "HL".

The congruent pair of legs would be the shared overlapping side EC. We can say that EC = EC due to the reflexive property. So we have the "L" of "HL"

Using BC = DC and EC = EC, we have enough information to use HL to prove triangle BEC is congruent to triangle DEC.

The city park department is planning to enclose a play area with fencing. One side of the area will be against an existing build
Oksanka [162]

Answer:

The maximum rectangular area will have the length 400 meters and width 200 meters with one side of the length against an existing building.

Step-by-step explanation:

From the given information;

The perimeter of a rectangle = 2 (L+B)

here;

L = the length of the side of the fence

B = the width of the fence

So; The perimeter of a rectangle = 2L+2B

we are also being told that;

One side of the area will be against an existing building

i.e

The perimeter of a rectangle is now =  L + 2B = 800 meters

L = 800 - 2B

Similarly; Area of a rectangle = L × B

Area of a rectangle = ( 800 - 2B) × B

Area of a rectangle =  800B - 2B²

assuming A(B) to represent the Area;

Then the maximum area A'(B) = 0 ;

Thus,

A'(B) = 800 - 4B = 0

-4B = - 800

4B = 800

B = 200

Therefore; the maximum area have a width = 200 meters and a length 800 - 2(200) =  800 - 400 = 400 meters
