Answer:

The anwer is A

Step-by-step explanation:

If it is a right angle triangle we use paythagoras theorem

a ×a + b× b= c × c

  • so we use the side which is straight to the 90° angle for the variable C. For variable A and B it doesn't matter we can use what we want.
  • so the side which is straight to the 90° angle is 17.
  • now let's substitute

1. 15× 15( square of 15) + b× b(square of b) = 17 ×17 (square of 17)

;2. 225 + b×b(square of b ) = 289

3. b×b(square of b) = 289-225

4. b × b( square of b )= 64

\sqrt{b \times b}  =  \sqrt{64}

b = 8

I hope it is helpful

Complementary events are the events which are opposite of the given event.

For example, for a "rainy day", its complimentary event is "not a rainy day".

We can also say, If A is a given event, then " not A" is its complimentary event.

In the given question we have been given the event of choosing a girl's name when drawing names from a cup in class.

Now in class as there can be boys or girls, the complimentary even of choosing a girl's name is choosing a boy's name.
