Answer:
<em>Similar: First two shapes only</em>
Step-by-step explanation:
<u>Triangle Similarity Theorems
</u>
There are three triangle similarity theorems that specify under which conditions triangles are similar:
If two of the angles are congruent, the third angle is also congruent and the triangles are similar (AA theorem).
If the three sides are in the same proportion, the triangles are similar (SSS theorem).
If two sides are in the same proportion and the included angle is equal, the triangles are similar (SAS theorem).
The first pair of shapes are triangles that are both equilateral and therefore have all of its interior angles of 60°. The AAA theorem is valid and the triangles are similar.
The second pair of shapes are parallelograms. The lengths are in the proportion 6/4=1,5 and the widths are in proportion 3/2=1.5, thus the shapes are also similar.
The third pair of shapes are triangles whose interior acute angles are not congruent. These triangles are not similar
Answer:
in terms of pi: 4500π units^3
decimal: 14137.16694 units^3 (ROUND TO THE NEAREST DECIMAL POINT BASED OFF OF THE QUESTION PROMPT!)
Step-by-step explanation:
FOR “IN TERMS OF PI” =
V = (4/3) (π) (15^3)
V = (4/3) (π) (3375)
V=4500π
FOR ACTUAL DECIMAL=
V = (4/3) (π) (15^3)
V = (4/3) (π) (3375)
V=4500π
V= 14137.16694 units^3
hope this helps! :)

Answer:
¼ cup of flour
Step-by-step explanation:
½ of ½ cup = ½×½ cup = ¼ cup
Step-by-step explanation:
1st way: 5x
2nd way: 5.x
third way: 5(x)
X is 63 degrees!
It is equal to the angle marked 63 degrees (angles in that arrangement are always equal)
