Question

Two ladders are leaning against a wall at the same angle, as shown. How long is the short ladder?

(two ladders, one is 60 and 40 and the other short ladder says 10).

6ft
15ft
20ft
30ft

Is it 15ft? Can someone explain to me how to solve it?

Answer 1

You are not telling us the other measurments, ie, the distance each ladder is up the wall, and the distance from the wall to the foot of the ladder.

You work this as SIMILAR triangles, using ratios.

Answer 2

either 60/40 = x/10 ==> x = 15

or 40/60 = x/10 ==> 6.67

So I guess you could be right.

Answer 3

so he did he get the answer or not

Answer 4

No beastboy he did not. He is no where near any of the answers in the question at all. The teacher here is so dumb.... 🤦

Answer 5

I forgot to respond.... but I’m pretty sure it 15....... but then again this was a month ago so idk

Answer 6

so... what is the answer?

Answer 7

The answer is 15 bc

she says the lengths are 60 inches 40 inches and 10 inches
the proportion would be 40/60 * 10/x
now you have to do cross multiplication.
So, you multiply 60*10
Which is 600
Then divide by 40
And you will get 15.
That's the answer!
(Also sorry if my grammar and spelling are bad.)
