<u>Answer:</u>
∠DBC = 40°
<u>Step-by-step explanation:</u>
We are given a figure where we know that the angle m∠1 = 65°, m∠2 = 60° and m∠6 = 85°. With the help of these given measures of the angles, we are to find the measure of the angle m∠DBC.
Since the sum of angles in a triangle is equal to 180 degrees, so:
∠1 + ∠2 + ∠3 = 180
∠3 = 180 - (65 + 60)
∠3 = 55°
Also ∠6 and ∠B are alternate interior angles so if ∠6 = 85° then ∠B is also = 85°.
Now that we know ∠3 and ∠B, we can find ∠DBC:
∠DBC = 180 - (85 + 55)
∠DBC = 40°

Put in calculator lol
Answer:
B
Step-by-step explanation:
The question says reflection across y = 1 so first find this line on the graph. It will be a horizontal line.
The Y axis is the vertical axis and so the 1 is the line right above the X axis.
So to reflect, it will be the same number away from the line when reflected as when it began on the opposite side of the line. So, S is one under the reflection line so it will be one above making its new point ( 2 , 2 )
Q is right on the line so it will not move.
R is two above the line so it will now be two below the line to have ( 3 , - 1 )
Answer:
The 7th term of the sequence is 0.000768
Step-by-step explanation:
As given, the sequence is : 12, -2.4 , 0.48, ....
The first term = 12
Second term = -2.4
Third term = 0.48
Common ratio =
Fourth term = 0.48(-0.2) = -0.096
Fifth term = -0.096(-0.2) = 0.0192
Sixth term = 0.0192(-0.2) = -0.00384
Seventh term = -0.00384(-0.2) = 0.000768
