Answer:

1. The sum of interior angles of a pentagon is 180 but here the sum of angles of this pentagon is 550 . So it is wrong.

2. Angle 145 is equal to the corresponding of angle y. So angle y is 145 degree.So according to opposite angle theorem, angle x is also 145 degree.

Sorry I do not know next question solutions.

Place the indicated product in the proper location on the grid. Place a 0 before the decimals. (0.1x + 0.4y)2

Nuetrik [128]

Answer:

$0.01x^{2} +0.08xy+0.16y^{2}$

Step-by-step explanation:

For the following expression

( $(0.1x + 0.4y)^{2}$ )}

First, write the multiplication factors:

$(0.1x + 0.4y)(0.1x + 0.4y)$

Then multiply by the first term 0.1x, and later by the second term 0.4y.

You can rewrite the multiplication like this:

$(0.1x + 0.4y)\\(0.1x + 0.4y)$ =

$0.01x^{2} + 0.04xy$

$+0.04xy + 0.16y^{2}$

-----> Now add similar terms and you will get:

$0.01x^{2} + 0.08xy + 0.16y^{2}$

If y is proportional to x, and y = 4 when x = 6, what is the constant of proportionality between them (the ratio of x to y)

topjm [15]

The ratio is 4/6. (If you need an equation: 6x=4)

Hope this was helpful.

Solve for x. Show all your work

olasank [31]

42°

Step-by-step explanation:

$\angle BAE =180\degree -132\degree$

(Angles in linear pair)

$\angle BAE =48\degree$

$\angle AEB =90\degree..(\because \overrightarrow{EC}\perp\overrightarrow{ED})$

$\angle ABE = 180\degree-(48\degree+90\degree)$

(Angle sum postulate of a triangle)

$\implies\angle ABE = 180\degree-138\degree$

$\implies\angle ABE = 42\degree$

$\angle CDE =\angle ABE = 42\degree$

(corresponding angles)

$\implies x\degree=\angle CDE$

(vertical angles)

$\implies x\degree=42\degree$

$\implies x=42$
