Answer:

z = 35

Step-by-step explanation:

Use the triangle angle sum theorem which states that the interior angles of a triangle sum to 180 degrees. The angles it refers to are the angle measures at each vertex. (Each point of the triangle)

You do not need x and y for this question. They are not angle measures at the vertex.

22+19+104+ z = 180. Combine like terms.

145+z= 180. Subtract 145 from both sides.

z= 35

AVprozaik [17]

Answer:

A.)lPace the compass needle on M and, keeping the compass width the same, draw two arcs that intersect

Step-by-step explanation:

In the construction of a line perpendicular to AB←→ and passing through an external point M the first step must be"Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect AB←→". After that you can draw arcs from intersection points (keeping the compass width same as before) to the opposite side of M, name it as N than use straightedge to draw line passes through M and n that would be perpendicular line to AB.

Which expression is equivalent to -3(4c-2) -2c

sergeinik [125]

Answer:

-3(4c-2) -2c = -14c+6

Step-by-step explanation:

We need to find the equivalent expression for -3(4c-2) -2c.

First we open the brackets as follows :

-3(4c-2) -2c

= -12c+6-2c

=-12c-2c+6

=-14c+6

So, the equivalent expression is -14c+6.

For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.

Trava [24]

11 = 1.375 * 8
22 = 1.375 * 16
33 = 1.375 * 24
Therefore y varies directly with x.
Answer: C ) yes; y = 1.375 x

A square park has an area of 6561 square meters. If you walk around the park what is the distance that you would have walked?

Paraphin [41]

First we have to find length of 1 side of the square. We can use formula for area of the square. A=a*a ==> $A=a^2$ where a is length of the side.
From this formula we can find
$a= \sqrt{A}$
a= $\sqrt{6561} =81 - 1 side$
Now we just have to multiply it by 4, because there are 4 sides.
81*4=324 - its the answer
