Answer:
Option (c) is correct.
Step-by-step explanation:
See the attached figure.
Here, x + y = 10 cm. ............ (1)
The height h divides the whole right triangle into two different right triangles.
If we consider the height as h, then applying Pythagoras Theorem,
h² = 6² - x² {From small triangle} ........... (2)
Again, from large triangle we can write,
h² = 8² - y² .............. (3)
Now, from equation (2) and (3) we can write
6² - x² = 8² - y²
⇒ 36 - x² = 64 - (10 - x)² {From equation (1)}
⇒ 36 - x² = 64 - 100 - x² + 20x
⇒20x = 72
⇒ x = 3.6 cm.
So, from equation (1) we get, y = 10 - 3.6 = 6.4 cm.
Therefore, option (c) is correct. (Answer)

Abstraction in mathematics is the process of extracting the underlying structures, patterns or properties of a mathematical concept, removing any dependence on real world objects with which it might originally have been connected, and generalizing it so that it has wider applications or matching among other abstract
Answer:
m =
Step-by-step explanation:
Given
c = 2m - 2c ( isolate 2m by adding 2c to both sides )
3c = 2m ( divide both sides by 2 )
= m
