Answer:
x usually goes on the x axis whereas y or the answer u can choose goes on y
Step-by-step explanation:
Answer:
x= 30
Step-by-step explanation:
The angles shown are corresponding, meaning that they are equal in measure. To find the answer, set x+25 equal to 55. Solve. x=30.
(x+25)=55
(30+25)=55
It would be 6,300 millimeters
Answer:
The correct option is O B'
Step-by-step explanation:
We have a quadrilateral with vertices A, B, C and D. A line of reflection is drawn so that A is 6 units away from the line, B is 4 units away from the line, C is 7 units away from the line and D is 9 units away from the line.
Now we perform the reflection and we obtain a new quadrilateral A'B'C'D'.
In order to apply the reflection to the original quadrilateral ABCD, we perform the reflection to all of its points, particularly to its vertices.
Wherever we have a point X and a line of reflection L and we perform the reflection, the new point X' will keep its original distance from the line of reflection (this is an important concept in order to understand the exercise).
I will attach a drawing with an example.
Finally, we only have to look at the vertices and its original distances to answer the question.
The vertice that is closest to the line of reflection is B (the distance is 4 units). We answer O B'
Step-by-step explanation:
first you need to know that angle 4 and angle d are the same measurement. so then you have to notice that a straight line is equal to 180 degrees. by knowing this you can make this equation
x+30+ 2x +15= 180
next combine like terms:
3x+ 45=180
next subtract 45 from both sides
3x=135
next divide by 3 on both sides to get x alone. this will give you your answer.
x=45
once you know this plug 45 into you equation to do d the value of the angle 4
