1. In Kite ABCD below, point E is the midpoint of segment BD. What are the

Anvisha [2.4K]

Answer:

The coordinates of point D( 4,4)

Step-by-step explanation:

Step(i):-

Given points are E(10,4) and B(16,4)

'E' is the mid-point of segment BD

Let D(x₁, y₁) be a point

E = midpoint of segment BD

$(10,4) = (\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )$

$10 = \frac{x_{1} +16 }{2}$

20 = x₁ + 16

20-16 = x₁

x₁ =4

Step(ii):-

$\frac{y_{1} +y_{2} }{2} = 4$

$\frac{4 +y_{2} }{2} = 4$

4 + y₂ = 8

y₂ = 8-4 =4

The co-ordinates of point D( 4,4)

I need help with properties of rhombus, rectangles and squares

Flauer [41]

Answer:

rhombus
x = 70
y = 5

Step-by-step explanation:

A quadrilateral with 4 same-length sides is a rhombus.

(If the corner angles are also 90°, then the rhombus is also a square. That is not the case here.)

Adjacent angles are supplementary, so ...

x° = 180° -110° = 70°

Sides are the same length, so ...

2y = y+5

y = 5 . . . . . subtract y

_____

If part of the picture was cut off, the right side of the figure may be something other than 2y. If so, formulate the equation appropriately and solve for y.

zavuch27 [327]

Answer: 15

Step-by-step explanation:

Since we are informed that in exchange for 5 eclaire boxes, that Luna gets, she decided to give 1 eclaire box for free.

Then, the number of eclaires boxes that they can buy from Luna using 77 claire boxes will be:

= 77 / 5

= 15 2/5

= 15 approximately

They'll get 15 boxes of eclaires from Luna.
