Answer:

1) In the given figure opposite sides are Parallel . Hence, it is a parallelogram.

2) Option (1) and (3) are correct.

Step-by-step explanation:

1)

  • Parallelogram is a two dimensional figure with opposite sides parallel and equal in length and diagonals bisect the angles.
  • Rectangle is  two dimensional figure with opposite sides equal in length and measure of each angle is 90° .
  • Square is  two dimensional figure with all sides equal in length and measure of each angle is 90°.
  • Rhombus is a two dimensional figure with all sides equal in length and sum of measure of opposite angle is 180°.

Thus, in the given figure opposite sides are Parallel . Hence, it is a parallelogram.

2)

The sufficient condition for  a parallelogram to be square is diagonals    are perpendicular and diagonals are congruent  and all the sides are congruent.

Thus, (1) and (3) are correct.

vfiekz [6]
<h3>Answer: x = 5</h3>

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

Work Shown:

Angle Bisector Theorem

9/(2x-1) = 15/3x

9*3x = 15(2x-1) ... cross multiply

27x = 30x-15

27-30x = 30x-15-30x ... subtract 30x from both sides

-3x = -15

-3x/(-3) = -15/(-3) .... divide both sides by -3

x = 5

How to find the area of composite polygon that have a base of 16 meters height of 18 meters and a height of 11 meters.
LenaWriter [7]

The area of the composite polygon is:

\boxed{A_{T}=376 \ m^2}

<h2>Explanation:</h2><h2 />

Hello! remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any figure, so I'll choose the figure below in order to illustrate this problem. A composite polygon is a polygon that can be divided into two or more basic shapes. So here we have a composite polygon formed by a triangle and a rectangle. So:

A_{total}=A_{T} \\ \\ A_{triangle}=A_{tr} \\ \\ A_{rectangulo}=A_{r} \\ \\ \\ A_{tr}=\frac{b\times h}{2} \\ \\ b:Base \ of \ the \ triangle \\ \\ h:height \ of \ the \ triangle \\ \\ \\ A_{r}=B\times H \\ \\ B:base \ of \ the \ rectangle \\ \\ H:height \ of \ the \ rectangle

So the area of the composite figure is:

A_{T}=\frac{16\times 11}{2} + 16\times 18 \\ \\ A_{T}=88+288 \\ \\ \boxed{A_{T}=376 \ m^2}

Alfred wants to waste less than 175 gallons of water this week. Every day that he waters the lawn, he wastes 59 gallons of water
victus00 [196]
L & C represent the number of days Alfred should water the lawn and wash his car respectively.
Each time he waters, there is 59 gallons used, and each time he washes car, 28 gallons used.

59L + 28C = 175 <the aim he set for himself>
59 gallons × L will then be the total amount of water he uses for watering lawn in a week.
28 gallons × C will then be the total amount of water he uses to wash his car every week.

The expression / answer : 59L + 28C = 175

Hope this helps! :)
