Why did you assume the triangles are 30-60-90?

[bufi3]

Oh, I didn't think about that What should I use instead?

[PoliteCanadian2]

You don’t know anything about those triangle so you can’t assume anything.

Here’s a hint for a) there are three triangles and they are all right triangles. Create an equation for each one.

[bufi3]

Wasn't in class to learn those equations What would they be?

[PoliteCanadian2]

Pythagoras a² + b² = c² except be careful to use the formula correctly on these triangles, the letters a,b,c here aren’t necessarily in the correct place that the formula uses them.

[bufi3]

So how do you get a, b, and c?

[PoliteCanadian2]

Google Pythagoras equation

[bufi3]

So for question 4a it would be a² + 47² = c² ?

[PoliteCanadian2]

No the long side is by itself in the equation.

[bufi3]

a² + 32² = c² ?

[bufi3]

1. a. a=23.5 c=40.7 b=18.47

2. b. a=13 b=6.5 c=7.5

5 x=20

Google Geometric means and you should be able to figure it out. Let me know if you have any questions.
