You are just meant to use the Pythagorean theorem.

Is that enough info?  

What does Pythagoras's theorem say?

That is great :)

Use desmos graphing calulator online.

Yes that is correct.  Good Work!

Give yourself a point    

1) First draw it.

2) Then think about the size of the angles that are mentioned. They are all the same and they're easy to find.

3) Then use known ratios to work out WZ

4) then again to work out ZB

5) Then find the area.

Follow my instructions and if you are stuck then tell me what you have done I can help more.

Please no one answer over me!

A club with five men and six women wish to form a committee. The number of men must be between 1 and 3 (inclusive), and the number of women must be between 2 and 4 (inclusive). How many different committees can be formed?

Choose 1, 2 or 3 men from 5

How many ways to choose 1?

How many ways to choose 2?

How many ways to choose 3?

How many possible ways to choose the men altogether?

Choose 2,3,or 4 women from 6

Continue as I did for the men.

Multiply the two answers together.

Now you try :)     Ask questions if you want.

No one else answer over me thanks.

There are more than 4 values.

1) First draw up a triangle that looks possible.  

  All the angles are different so if you use a triangle that looks a bit like a 30,60, 90 degree triangle that will be good to work with.

2)  Label the 3 angles correctly according to their relative angle size

3)   Label the 3 sides 

4)   Now the smallest side is opposite the smallest angle etc so write 'smallest' and 'biggest' near the correct sides.

5) Now you know that smallest side < middle side      Solve the inequality

6) You also know that the middle side < longest side.   Solve the inequality.

7) So what do you know so far?

8) Now to be a triangle at all the sum of the 2 smallest sides must be longer than the long side.

   Form the inequality and solve it.

9) So what have you found.

If you have questions then ask.     You can take a photo of your pic on your phone and post it if need be. 

I am very happy to help more if necessary but i want to be convinced that you are trying to help yourself first.

Please no one else answer
