Length(l)= 4+ w
Width(w)=w
Area(A)= 21m^2
so keep in mind Area= Length × width
A= l×w
21=(4+w)(w)
21= 4w+ 2w
21=6w
w=3.5
The width is 3.5m
so the answer is about 4m
Answer:
A composition of transformations is a combination of two or more transformations.A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines.
Step-by-step explanation:
Answer: the formula is (A=bh1/2)
Step-by-step explanation: #4 (The triangle)
First let’s find the base length of the triangle.
28 - 16 = 12
Ok now let’s do the real math now
Area = bh1/2
Area = (12)(16)(1/2)
Area = 96

The angle of rotation of triangle ABC to A'B'C is 105°
<h3>How to illustrate the information?</h3>
It should be noted that the rotation from ABC to A'B'C is in a clockwise direction.
Point B is also on the x axis and point B' is in the second quadrant.
In this case, the angle that depicts the second quadrant is 105°.
In conclusion, the correct option is D.
The complete question is:
Triangle A’ B’ C’ is the image of A B C under a rotation about the origin, (0,0)
Determine the angle of rotation
A. -105 degrees
B. -75 degrees
C. 75 degrees
D. 105 degrees
