Answer:
Error was CHOOSING the CORRECT hypotenuse in the given sides.
H = 41 units
Step-by-step explanation:
Here, the given sides of the triangle are: 41,40 and 9
Now, as we know in a RIGHT ANGLED TRIANGLE:
The longest side is the HYPOTENUSE.
So, here H = 41
Now, by PYTHAGORAS THEOREM:
Hence, Pythagoras theorem for Right angled triangle is SATISFIED
So, error was CHOOSING the CORRECT hypotenuse in the given sides.
The correct H = 41 units and NOT 40 units.
Answer:
k = (1 , 4)
Step-by-step explanation:
here's your solution
==> k^2 - 5k + 4. [ is expression ]
==> by using middle term split
==> k^2 - 4k - k + 4
==> taking common from each
==> k(k - 4) - 1 (k - 4)
==> (k - 1) , (k - 4).
==> k - 1 = 0
==> k = 1
==> k - 4 = 0
==> k = 4
hence , k = (1 , 4)
hope it helps
