quadratics or geometry?..

[gleaming crystal]

Uhm im not sure how I got these wrong.. what would be the right answers?

[terse garnet]

@gleaming crystal for this one you added rather than subtracting

AC is the hypoteneus

[gleaming crystal]

so it’d be 12

?

[terse garnet]

so to solce for BC you rearrance 12^2 + (BC)^2 = 24^2 to get BC^2 = 24^2 - 12^2

[gleaming crystal]

oh

where does root?

[terse garnet]

to reduce the power of the constant

[gleaming crystal]

Ohh

What about the others?

[scarlet wagon]

@gleaming crystal you could use Pythagoras theorem

[gleaming crystal]

no

I don’t know how

Is this it

[gleaming crystal]

Ohh

What’s the answer to the other 3? And what equation

Would I use the same

[novel yoke]

for this one, do you know what a zipline is? @gleaming crystal

[gleaming crystal]

yes

[novel yoke]

So the zipline will be strung or installed between two trees.

pls dont mind the drawing hahahaha. just to visualize it

then trees are 52 ft apart. the word problem asks for the length of the zipline.

[ember shadow]

I think 32 feet is the height from ground

[novel yoke]

That's also what I'm thinking. but is it not in the choices tho

[ember shadow]

The last option

[novel yoke]

i dont think so since it is in the middle

[ember shadow]

It seems like the whole length

[novel yoke]

oh yeah. got it

[analog nacelle]

This is a right angled triangle with hypotenuse 55 and base 27, use Pythagoras theorem @gleaming crystal

[gleaming crystal]

okay!
so

x + 27^2 = 55^2

[novel yoke]

almost.

x²+27² = 55²

[analog nacelle]

this is correct @gleaming crystal

[gleaming crystal]

ohh
