find z and x

please help i’ll mark the first one or whoever right brainliest

Answers

Answer:

z=97 x=21

Step-by-step explanation:

so straight angles always equal 180°

And assuming that your lines are parallel, the angle under angle z should be 83° just like the angle above angle z

There for to solve for x, first subtract 83 from 180 because that's what that angle is equal to.

Now that you have the equation 4x+13 and you know that it's equal to 97 you can solve it just like a normal inequality.

4x+13=97

4x=84

x=21

Answers

Answer:

B, because it’s Angle Angle, or (A,A)

The given triangles are similar by AA rule of similarity.

What is triangle similarity?

If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar.

Given are two triangles,

AA rule of similarity:

If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.

Here we see,

∠ K ≅ ∠ Y

∠ J ≅ ∠ X

Hence, we can say that, both are similar by AA rule.

write the linear equation from the given information in slope intercept form passing through (-2,8) and perpendicular to y=2x+5​

Answers

Answer:

y  =  [tex]-\frac{1}{2}[/tex] x + 9

Step-by-step explanation:

Given parameters:

  Coordinates = (-2,8)

Equation of the line  y  = 2x + 5;

Unknown:

Linear equation of a line perpendicular = ?

Solution:

From the given expression, a line perpendicular will have a negative inverse of the slope given.

           y  = 2x + 5

Equation of a line  is y = mx + c;

y and x are the coordinates

  m is the slope

   c is the intercepts

    y  = 2x + 5 ;

 The slope is 2;

  A line perpendicular will have a slope of [tex]-\frac{1}{2}[/tex]  

 Since y = 8 and x  = -2, let us find c;

     8  = 2 x [tex]-\frac{1}{2}[/tex]  + c

    8 = -1 + c

     c  = 8+1 = 9

The equation of the line is;

       y  =  [tex]-\frac{1}{2}[/tex] x + 9

Nikki just graduated from high school and would like to buy a car. If she received $3000 in graduation gifts from family friends. She will put this money into a 18 month certificate of deposit until she finds the car of her dreams. The CD earned 10% annually and simple interest. How much will she put towards the down payment and 18 months 1.5 years?

Answers

Answer:

$3450

Step-by-step explanation:

Here, P = $3000, N = 1.5 years, R = 10%

[tex]SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\ [/tex]

Amount of down payment

= $3000 + $450

= $3450
