Answer:

The angle z is 130 degrees.

Step-by-step explanation:

A straight line is 180 degrees.

Now think about how that line looks, you cut 50 degrees off of the whole 180.

So the equation is 180-50=z

z=130

I hope I have been of assistance to you, have a good day.

$\huge \bf༆ Answer ༄$

The Angles shown in the diagram makes linear pair on the straight line [ hence, their sum measures 180° ]

that is ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:z + 50 = 180$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:z = 180 - 50$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:z = 130 \degree$

Hence, required value of z is 130°

The lengths of the bases of the right trapezoid are 9 cm and 18 cm. The length of a longer leg is 15 cm. Find the area of the tr

finlep [7]

Firstly, we will draw figure

now, we will draw a altitude from B to DC that divides trapezium into rectangle and right triangle

because of opposite sides of rectangle ABMD are congruent

so,

DM=AB=9

CM=CD-DM

CM=18-9

CM=9

now, we can find BM by using Pythagoras theorem

$BM=\sqrt{BC^2-CM^2}$

now, we can plug values

we get

$BM=\sqrt{15^2-9^2}$

$BM=12$

now, we can find area of trapezium

$A=\frac{1}{2} (AB+CD)*(BM)$

now, we can plug values

and we get

$A=\frac{1}{2} (9+18)*(12)$

$A=162cm^2$

so, area of of the trapezoid is $162cm^2$ ..........Answer

Which of the following inequalities best represents the graph above?

Montano1993 [528]

The inequality n ≥ 9 properly represents the graph because the arrow is pointing to the right of 9, and the dot is filled in on 9, representing Greater than or equal to.
Hope that helped!

Can anyone help me figure out the answer to this

Alex17521 [72]

3x-11=17-4x add 4x to both sides

7x-11=17 add 11 to both sides

7x=28 divide both sides by 7

x=4
