by the pythagorean theorem, we can say (FP)^2 + (OP)^2 = (OF)^2 10^2 + 14^2 = r^2 solve for r and tell me what you get

100 + 196 = 296^2. Now what?

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
r^2 = 296 so r = ???

no

don't square it though

you did sqrt(296) right?

it's close, but not correct

17.2 isn't one of the answers. Only 16.9

but remember, we want x, not r

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
we use r to get x

\[\large r = \sqrt{296} \rightarrow r^2 = 296\] \[\large (OQ)^2 + (RQ)^2 = (OR)^2\] \[\large (OQ)^2 + (RQ)^2 = r^2\] \[\large x^2 + 12^2 = 296\] \[\large x^2 + 144 = 296\] ... ... ... \[\large x = ???\]

\[\large x^2 = 152\] so \[\large x = ???\]

good, x is roughly 12.3

What about this one?

what about it? what do you want to find? and what are you given?

Emily778 Group TitleBest ResponseYou've already chosen the best response.1
Oh. Lol. Forgot.\ AB is a diameter and AB is perpendicular to CD.

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
alright so that's all the given info?

I know the angles are all 90 degrees.

what do you need to find exactly?

Find BD for AC= 58 DEGREES
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
AC is a segment, not an angle
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so is it ACP or ACB that's 58 degrees
 one year ago

Emily778 Group TitleBest ResponseYou've already chosen the best response.1
This is exactly what it says. Find m BD for m AC= 58 degrees.
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
oh arc AC, gotcha
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
angle APC = (1/2)*(arc AC + arc BD) 90 = (1/2)*(58 + x) 90*2 = 58 + x 180 = 58 + x solve for x
