Answer:
The two triangles are similar because as the SSS similarity theorem states " two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional". While XYZ is larger than ABC, the two triangles have corresponding angles and sides.

Answer:
32 squared units
Step-by-step explanation:
The composite given in the figure consist of 3 triangles and 1 square shape.
To calculate the area of the composite shape, let's calculate area of each shape and then add all together.
==>Area of the square (Q): s²
s = 2
Area = 2² = 4 squared units
==>Area of biggest triangle (B): ½*b*h
b = 2+2+6 = 10
h = 4
Area = ½*10*4 = 5*4 = 20 squared units
==>Area of medium triangle (M): ½*b*h
b = 2
h = 6
Area = ½*2*6 = 6 squared units
==>Area of smallest triangle (S): ½*b*h
b = 2
h = 2
Area = ½*2*2 = 4/2 = 2 squared units
==>Area of composite shape = Q+B+M+S = 4+20+6+2 = 32 squared units
The answer I believe is D. BC is congruent to DF
Answer:
44.1
Step-by-step explanation:
Pls brainiest
9*4.2=first rectangle area=37.8
3*4.2/2=small triangle=3*2.1=6.3
37.8+6.3=44.1
