Answer:

√[ (a + b)^2 + c^2 ].

Step-by-step explanation:

They are both equal in length because we have an isosceles trapezoid here. We see form the drawing it is symmetrical about the y axis.

The diagonal = the line joining points (b, c) and (-a, 0)

= √[ (b - -a)^2 + (c - 0)^2 ]

= √[ (a + b)^2 + c^2].

Are randomly choosing a person who is left-handed and randomly choosing a person who is right-handed mutually exclusive events?

Masteriza [31]

Answer: No .

Step-by-step explanation:

There are special cases where a person can use right and left hand equally well . I.e ambidextrous .

In statistical terms and probability theory, two events (or propositions) are mutually exclusive or disjoint if they cannot both occur at the same time .however in this case it may occur that the person is right and left handed at the same time .
