Triangle BAD is a rotation of triangle DCB around point E by 180 degrees.
Andrews [41]

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>

The sum of two numbers is 82. One number is three less than four times the other. Find the two numbers.
kondor19780726 [428]

Answer:

17 , 65

Step-by-step explanation:

x+ y = 82

y = 4x - 3

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

Put the second equation into the first.

x + 4x - 3 = 82

5x = 85

x = 85/5

x = 17

17 + y = 82

x = 82 - 17

x = 65

Eight more than the quotient of a number and 9 is equal to 3.​
kakasveta [241]

Answer:

-45

Step-by-step explanation:

Let the number be represented by x.

The question can be solved as x/9 + 8 = 3

This is because the quotient of the number and 9 is same as (x/9)

and it is expected to be eight more (+ 8)

Therefore, x/9 = 3 - 8

x/9 = -5

x = -5 x 9

x = -45
