Here is the table with the filled in answers
Answer:
33.08 m
Step-by-step explanation:
angle of ∆ = 131.6 - 90 = 41.6
=> x² = 8²+3²-2(8)(3)cos 41.6°
= 64+9-48(0.75)
= 73 - 36
= 37
x = √37 = 6.08 m
perimeter = (3×8)+3+6.08 = 33.08 m
Answer:
C'(4, 0)
Step-by-step explanation:
Translated 6 units to the right means that the x-value increases by 6.
1 unit up means y-value increases by 1.
(-5 + 6, -1 + 1)
(-2 + 6, -1 + 1)
The second point must be C, as the translation lines it up with one of the answers.
The given conclusion that ABCD is a square is not valid.
Given that, AC⊥BD and AC≅BD.
We need to determine if the given conclusion is valid.
<h3>What are the properties of squares?</h3>
A square is a closed figure with four equal sides and the interior angles of a square are equal to 90°. A square can have a wide range of properties. Some of the important properties of a square are given below.
- A square is a quadrilateral with 4 sides and 4 vertices.
- All four sides of the square are equal to each other.
- The opposite sides of a square are parallel to each other.
- The interior angle of a square at each vertex is 90°.
- The diagonals of a square bisect each other at 90°.
- The length of the diagonals is equal.
Given that, the diagonals of a quadrilateral are perpendicular to each other and the diagonals of a quadrilateral are equal.
Now, from the properties of a square, we understood that the diagonals of a square are perpendicular to each other and the diagonals of a square are equal.
So, the given quadrilateral can be a square. But only with these two properties can not conclude the quadrilateral is a square.
Therefore, the given conclusion that ABCD is a square is not valid.
