Answer:
A. 
by the SAS postulate.
Step-by-step explanation:
We have been two triangles. We are asked to determine the theorem by which both triangles could be proven congruent.
We can see that side DF of triangle DEF is equal to side AC of triangle ABC.
We can also see that side BC of triangle ABC is equal to side EF of triangle DEF.
The including angle between sides AC and BC of triangle ABC is equal to the including angle between sides DF and EF of triangle DEF.
Since both triangles have two sides and their included angles equal, therefore, triangle ABC is congruent to triangle DEF by SAS (Side-Angle-Side) congruence and option A is the correct choice.
Answer:
102.40 ft
Step-by-step explanation:
This system can be described as a right triangle with the horizontal distance from the silo (80 ft) being the side adjacent to the 52-degree angle, and the height of the silo (h) being the side opposite to the angle. Therefore, the height can be found by:
The silo is 102.40 feet tall.
The simplest symmetry<span> is Reflection </span>Symmetry<span> (sometimes called </span>Line Symmetry<span> or Mirror </span>Symmetry<span>). It is easy to see, because one half is the reflection of the other half.</span>
38%
95 divided by 250 is 0.38. Multiply 0.38 by a hundred and you get 38%
Plane
Plane is an undefined geometric term possessing 2 dimensions; Length and width.
Planes extend infinitely therefore if has no beginning nor end.
