You can print a copy of the graph, stick a pin in the origin, and rotate it 180° to see where the figure ends up.

The origin is the midpoint between each vertex and its image.
Negate every coordinate value, for example, J(-5, -3) gets rotated to J'(5, 3).

Question 18
Svetlanka [38]

Answer:

Step-by-step explanation:

J and K are equal

8x - 23 = 6x + 11            Add 23 to both sides

8x = 6x + 11 + 23           Combine the right

8x = 6x + 34                  Subtract 6x from both sides

8x - 6x = 34                   Combine the left

2x = 34                           Divide by 2

x = 34/2

x = 17

=================================

M and L are both supplementary to J and K respectively.

J = 8x - 23

J = 8*17 - 23

J = 136-23

J = 113

K = 113

===================================

M + 113 = 180

M = 180 - 113

M = 67

L = 67

I don’t understand how this question
Vladimir79 [104]

Answer:

<u>x = √51</u>

Step-by-step explanation:

The given figure is a <u>right triangle</u>.

<u>Using the Pythagorean Theorem to find x</u>

  • (Altitude 1)² + (Altitude 2)² = (Hypotenuse)²
  • (7)² + x² = (10)²
  • 49 + x² = 100
  • x² = 51
  • <u>x = √51</u>
