ANSWER
45.6cm to the nearest tenth.
EXPLANATION
The diagonal of the rectangular painting is 62cm.
The height of the painting is 42 cm.
The height of the painting h , the diagonal, and the width of the painting forms a right triangle with the diagonal being the hypotenuse.
From the Pythagoras Theorem,
![{w}^{2} + {42}^{2} = {62}^{2}](https://tex.z-dn.net/?f=%20%20%7Bw%7D%5E%7B2%7D%20%20%2B%20%20%7B42%7D%5E%7B2%7D%20%20%3D%20%7B62%7D%5E%7B2%7D)
![{w}^{2} = {62}^{2} - {42}^{2}](https://tex.z-dn.net/?f=%20%7Bw%7D%5E%7B2%7D%20%3D%20%7B62%7D%5E%7B2%7D%20-%20%20%7B42%7D%5E%7B2%7D)
![{w}^{2} = 2080](https://tex.z-dn.net/?f=%20%7Bw%7D%5E%7B2%7D%20%20%3D%202080)
![{w} = \sqrt{2080}](https://tex.z-dn.net/?f=%20%7Bw%7D%20%3D%20%20%5Csqrt%7B2080%7D%20)
![w = 4 \sqrt{130}](https://tex.z-dn.net/?f=w%20%3D%204%20%5Csqrt%7B130%7D%20)
The width of the painting is 45.6cm to the nearest tenth.
Answer: The angles of ΔA'B'C are congruent to the corresponding parts of the original triangle.
Step-by-step explanation:
Given : Triangle ABC was rotated 90 degrees clockwise. Then it underwent a dilation centered at the origin with a scale factor of 4.
A rotation is a rigid transformation that creates congruent images but dilation is not a rigid transformation, it creates similar images but not congruent.
Also, the corresponding angles of similar triangles are congruent.
Therefore, The angles of ΔA'B'C are congruent to the corresponding parts of the original triangle.
The common ratio of the given geometric sequence is the number that is multiplied to the first term in order to get the second term. Consequently, this is also the number multiplied to the second term to get the third term. This cycle goes on and on until a certain term is acquired. In this item, the common ratio r is,
r = t⁵/t⁸ = t²/t⁵
The answer, r = t⁻³.
The next three terms are,
n₄ = (t²)(t⁻³) = t⁻¹
n₅ = (t⁻¹)(t⁻³) = t⁻⁴
n₆ = (t⁻⁴)(t⁻³) = t⁻⁷
The answers for the next three terms are as reflected above as n₄, n₅, and n₆, respectively.
If the original side length is "s" and the original slant height is "h", the original surface area is
.. S = (base area) +(lateral area)
.. S = s² +(1/2)*(4s)*h
.. S = s(s +2h)
Now, if we make these replacements: s ⇒ 3s, h ⇒ h/5, we have
.. S' = (3s)(3s +2h/5)
.. S' = 9s² +(6/5)s*h . . . . . . . the formula for the modified area (in terms of original dimensions)
_____
Of course, in terms of the modified dimensions, the formula is the same:
.. S' = s'(s' +2h')
