step-by-step explanation:
You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.
The answer: a) 386208
And you can see the method solution
Note: don't forget put heart ♥️ .
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>

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
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
