The line of reflection is b
You can see it much easier if take away all the clutter. Redraw the diagram and take way a d and especially c.
You should be left with only line b and the two triangles. You can see it much easier if you do that. Then just look at the parallel lines of the triangles. They are right across from each other.
Let the number be n. Then 2(n-10) = 6n + 14.
Multiplying out the left side, 2n - 20 = 6n + 14. Thus, -34=4n, and n = -17/2.
Answer:
Perimeter = 32.44 units
Area = 30 square units
Step-by-step explanation:
Given
Vertices
A(2,8), B(16,2) and C(6,2)
WE have to determine the lengths of all sides before finding the perimeter and area.
The formula of modulus is:
So the perimeter is:
Using hero's formula,
Rounding off will give us 30 square units ..
Answer:
60
Step-by-step explanation:
40+ 20
60
this is your answer
Answer:
Line DG is equal to 16
Step-by-step explanation:
We know that
In a parallelogram, opposite sides are congruent.
Line DG is congruent to line FE, so they must have sides of equal length.
4z-48=z
4z=z+48
3z=48
48/3=z
16=z
Now we know that the variable is 16 increments, so we sub the 16 in for z in line DG
4(16)-48
64-48=16
Line DG is equal to 16
