Question

find the value of x, if necessary round your answer to the nearest tenth

Answer 1

can you tell if any of those segments is the radius? what do you think? PD? PC? or maybe PA or PB?

Answer 2

notice that all those segments PA, PB, PD and PC originate from the center of the circle, and touch the circle, meaning all of them are radius to the circle, meaning all of them are of equal length

now, notice the tickmark on DC and AB? what does that mean?

Answer 3

that theyre equal?

Answer 4

im not sure to be honest

Answer 5

yes

Answer 6

whats the value of x though?

Answer 7

anyhow, the tickmark means both lines with it, are equal to each other

so, now we know that, all other segments equal each other and the other 2 lines are equal to each other too

so PD = PA, PC=PB and DC = AB

SSS side side side, both triangles are congruent and thus their angles are also congruents

Answer 8

thank you :D can you help me with a few more?

Answer 9

just post anew, so we can all help, more exposure will give more answers, and we also can revise each other :)
