Question

The design for a stage is shown below. The walking ramp, PS, is 12 inches in length.

Answer 1

I think its c=24

Answer 2

sin 60 = 12 / RP so, RP = 12 / sin60 sin60 = sqrt(3)/2 Substitute and Simplify. Rationalize the denominator.

Answer 3

okay, so then its A. am I correct?

Answer 4

Yes! Good work!

Answer 5

thank you :) can you help me with one more question?

Answer 6

Sure, why not? And thx for the recognition btw.

Answer 7

Np :)

Some steps in a geometric construction done by Lohan are shown below. The arcs at A and B are drawn from points L and M.

Answer 8

It's the last one.

Answer 9

Thanks! but how did you get that?

Answer 10

Ok, let's talk about that.

Answer 11

Okay. so explain please

Answer 12

So, AL, LB, BM, and MA will all have the same length, so you will have a rhombus, special type of parallelogram. LM is one diagonal and AB will be the other diagonal which will end up being perpendicular.

Answer 13

Oh okay! thanks so much!

Answer 14

Also, using the Pythagorean theorem AO^2 + OM^2 = AM^2. You can get a similar relationship with OAL.

Answer 15

You're welcome! And good luck in your studies!

Answer 16

thanks! big help! Im sorry to bother but can you help me with one last one. if not its okay. I posted it a few minutes ago.
