Answer:
A. x = 5 (Equation below)
B. AC = 9 | BD = 9
Step-by-step explanation:
A. Since we know the diagonals of an isosceles trapezoid are congruent, we know that the two bottom parts of the diagonal BD (2x - 8 and x - 4) are congruent to the diagonal AC (x + 2) . This means you can just equal them together and get the value of x:
2x - 8 + x - 4 = x + 2
3x - 12 = x + 2
3x = x + 14
2x = 14
x = 7
B. Just plug in 5 for x:
AC = x + 2 = 7 + 2 = 9
BD = 2x - 8 + x -4 = 3x - 12 = 21 - 12 = 9

When figures are congruent, they have the same shape and size. All measures of one of the figures are identical to the corresponding measures of the other.
Of these statements, the following must be true ...
- B. The corresponding sides of the triangles are congruent
- C. The corresponding angles of the triangles are congruent
- D. The triangles have the same shape and size
Answer:
The diameter of Circle P is the same length as the radius of Circle Q.
Step-by-step explanation:
The radius of Circle Q is half of 52cm. So you would divide 52 by 2 and get 26cm as the radius of Circle Q. Therefore, the length of the diameter of Circle P is the same length as the radius of Circle Q.
Slope is defined simply as delta y over delta x or the change in y over the change of x. We need to decided what points is going to be the start or the end. Typically, the point farther to the right of the graph is considered the end point.
Start: (1, 7)
End: (10, 1)
