We have a number .
To write it as a fraction first count the number of decimals and call it (which, in our case, has a value of 3). Multiply the number with
to get
. Then divide this number by
to get
from here you can either simplify (if the assignment says so, then the simplified fraction is
) or not.
Hope this helps.
Answer:
Option (4)
Step-by-step explanation:
Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).
Slope of XY () =
=
() =
Similarly, slope of XZ () =
() = (-1)
Which should be (-1) if XY and XZ are perpendicular to each other.
Now we can say that XY and XZ are not perpendicular.
Therefore, Lydia's assertion that ΔXYZ is a right triangle is not correct.
Option (4) will be the answer.
