Answer:
A. 10 B. 15
Step-by-step explanation:
A. 25/1 * 2/5= 50/5
reduced it is 10
B. 25-10=15
The triangle KLM is rotated about origin by 90 degrees to form the triangle K'L'M'.
<h3>What is a transformation of geometry?</h3>
A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.
Rotation does not change the size and shape of the geometry.
The triangle KLM is rotated about origin by 90 degrees to create the triangle K'L'M'.
The diagram is given below.

![\large \begin{aligned}\cos^2 \theta + \sin^2 \theta & = 1\\\implies \quad \quad \sin^2 \theta & = 1 - \cos^2 \theta\\\\\tan \theta=\dfrac{\sin \theta}{\cos \theta} \end{aligned}](https://tex.z-dn.net/?f=%5Clarge%20%5Cbegin%7Baligned%7D%5Ccos%5E2%20%5Ctheta%20%2B%20%5Csin%5E2%20%5Ctheta%20%26%20%3D%201%5C%5C%5Cimplies%20%5Cquad%20%5Cquad%20%5Csin%5E2%20%5Ctheta%20%26%20%3D%201%20-%20%5Ccos%5E2%20%5Ctheta%5C%5C%5C%5C%5Ctan%20%5Ctheta%3D%5Cdfrac%7B%5Csin%20%5Ctheta%7D%7B%5Ccos%20%5Ctheta%7D%20%5Cend%7Baligned%7D)
Therefore, using the <u>identities</u>, the given expression can be <em>simplified</em> as follows:
![\large\begin{aligned}\implies \dfrac{1- \cos^2 \theta}{\cos^2 \theta} & = \dfrac{\sin^2 \theta}{\cos^2 \theta}\\\\& = \tan^2 \theta\end{aligned}](https://tex.z-dn.net/?f=%5Clarge%5Cbegin%7Baligned%7D%5Cimplies%20%5Cdfrac%7B1-%20%5Ccos%5E2%20%5Ctheta%7D%7B%5Ccos%5E2%20%5Ctheta%7D%20%26%20%3D%20%5Cdfrac%7B%5Csin%5E2%20%5Ctheta%7D%7B%5Ccos%5E2%20%5Ctheta%7D%5C%5C%5C%5C%26%20%3D%20%5Ctan%5E2%20%5Ctheta%5Cend%7Baligned%7D)
albums: 15*7 = 105 cards
packages : 8*13 = 104 cards
extra cards 10
total cards =albums+ packages + extra cards
= 105+ 104 + 10
219 cards
