Answer:
b=
Step-by-step explanation:
Considering the given figure the sides 'b' , '2' and '5' are making the sides of a right angled triangle in the top right corner of the square, where
Hypotenuse=5 , Perpendicular=b and Base=2
Using Pythagoras Theorem:
Implementing the values in the formula:
So, the value of 'b' is which is same for the the given 'b' in the figure.
We are looking for the probability :
Transform the law to standard normal like this:
The above formula is equivalent to this one:
From normal law table, we read the value of
.
Solving the above equation for the score n:
, it is the score we are looking for.

Answer:
. It means AC is perpendicular to AB.
Step-by-step explanation:
Vertices of given triangle are A(−2, −2), B(5, −2), and C(−2,22).
Distance formula:
Using distance formula we get
According to Pythagoras theorem
Perpendicular = AC
Base = AB
It means AC is perpendicular to AB.
Hence proved.
