Triangle BAD is a rotation of triangle DCB around point E by 180 degrees.

Mathematics
1 answer:
Andrews [41]2 years ago
5 0

Taking point <em>Z </em> as the origin, the coordinates of the points on ΔBAD are

given by changing the sign of the coordinates of points in ΔDCB.

  • The angle that is congruent to ∠DBA is; <u>D. ∠BDC</u>

Reasons:

The given parameters are;

Triangle ΔBAD is the image of ΔDCB following a rotation of 180°.

Required:

The angle congruent to ∠DBA.

Solution:

Given that the rotation of triangle DCB is 180°, we have that the

coordinates of a point (x, y) in ΔDCB is (-x, -y) in ΔDBA.

Therefore, side DC is parallel to side AB

Which gives;

∠DBA is congruent to ∠BDC by alternate interior angles theorem.

∠DBA ≅ ∠BDC

The angle that is congruent to ∠DBA is; option <u>D. ∠BDC</u>

For the following true conditional statement, write the converse. If the converse is also true, combine the statements as a bico
Licemer1 [7]
Original Statement: If x = 3, then x^2 = 9 (true)

Converse: If x^2 = 9, then x = 3 (false; this is half the story and x = -3 must be included)

Since the converse isn't completely true, we can't combine the two statements to get a biconditional.

Find the length of the diagonal, round to the nearest tenth (( please answer, ill give brainliest))​
Lilit [14]

Answer:

Length of diagonal in the first top figure is 13 yd

Okay for this one, the formula of a diagonal in a cuboid is the root of sum of squares

length, breadth and height

so

D = root of 12^2 + 4^2 + 3^2

D = root of 144 + 16 + 9

D = root 169

D = 13yd

Length of diagonal in the bottom figure is 10.77 which is 10.8m

For this one, you have to find the diameter of base first

Since radius of the base is 5 diameter = 10

Since its a right angled triangle, Hypotenuse square = sum of sides square

Diagonal^2 = 10^2 + 4^2

D^2 = 100 + 16

D^2 = 116

D = root 116

D = 10.77

D = 10.8 m
