Answer:
a) The coordinates of the missing vertex = (7, 8)
b) Area = 18 square units
Perimeter = 18 units
Step-by-step explanation:
a) We know three of the four vertices:
A: (4, 2) C ______ D(?)
B: (7, 2) | |
C: (4, 8) A |______| B
To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:
Hence, the distance of point D from point C in the x-direction is:
Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:
Then, the distance of point D from point B in the y-direction is:
Therefore, the coordinates of the missing vertex (point D) are:
b) The area of the rectangle is:
The perimeter is given by:

Answer:
∠ Y = ∠ V
∠ Z = ∠ W
Step-by-step explanation:
It is given that Δ XYZ is similar to Δ XVW.
Since corresponding angles of similar triangles are equal,
∠ X = ∠ X
∠ Y = ∠ V
∠ Z = ∠ W
Also, since corresponding sides of similar triangles are in proportionate,
Hello the answer would be 18
Explanation:
lines KH and JK are congruent.
Line KH=c+18
Line JK=2c
2c=36 divide by 2
c=18
I don’t know how to explain it any other way.. sorry if you don’t understand but mark my answer as brainliest if it helped you out, please.
Answer:
Simplify the expression.
58
Step-by-step explanation:
Answer:
227 sides
Step-by-step explanation:
The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:
40500 = 180(n-2)
225 = n-2
227 = n
Therefore, the number of sides in the regular polygon is 227.
