1. Just substitute what's given into the formula.
2. Notice how both triangles have a common side. Try expressing it first.

[rustic prism]

Im to dumb for this..

[abstract canopy]

I mean, I'm not sure what else to say about 1. That's just it, substituting values into the formula.

[rustic prism]

I subbed it but then when i did the maths to see how much was made it was wrong,

[abstract canopy]

Can you show what you did?

[rustic prism]

Uh

I did it mentally lol

Im more ofa mental maths guy

[abstract canopy]

I mean, I don't think you mentally calculated a 30th power...

[rustic prism]

I mean i used a calc for that

[abstract canopy]

Oh.
Can you show what you typed in, then?

[rustic prism]

2000 pounds on a annual interest rate of 2.8% a year for 30 years

This but in calculator form

I did 2000 x 0.028 and then timed by 30

[abstract canopy]

Wait, no, that's not correct.

[rustic prism]

Oh

[abstract canopy]

You're already given the formula. Just substitute the values.

[rustic prism]

Wait so all i need to do is S = 2000 (1 + 2.6/100)

[abstract canopy]

Don't forget the power.

[rustic prism]

I didnt see that oops

What would it be a power to?

30?

[abstract canopy]

Yes.

[rustic prism]

so

This?

[abstract canopy]

Yes.

[rustic prism]

ty

[rustic prism]

ty SM

[abstract canopy]

What did you get?

[rustic prism]

£4319.67

[abstract canopy]

Yeah, that's right.

[rustic prism]

Ty!

[rustic prism]

Do you know what i should do with this one?

[abstract canopy]

Express the length of the common side first.

Better to denote the given and the common sides by something. a and b, for example.

[rustic prism]

Could you dumb it down a bit,,

[abstract canopy]

I don't know how else to say it.

[rustic prism]

i just dont understand what you mean lol

[rustic prism]

So

i know 3.4 side is A and one on left is H

And the line with 63 on must be the O

[abstract canopy]

What's O?

And H.

[rustic prism]

Hypotenuse

and Opposite

[abstract canopy]

Uh... Not sure why you'd denote them relative to just some angle.

[rustic prism]

Well if dont have all my angles dont i need to>

[abstract canopy]

I'd probably denote it like this.
You're given a, α and β, and you need to find y.

[rustic prism]

yep

But how do i do that?

cause trig is a bit blurry to me

[abstract canopy]

You should review trigonometric ratios, then.
