what is the value of p ?

OpenStudy (wolf1728):

Gee - do you just want people to guess?

OpenStudy (anonymous):

theres the picture

OpenStudy (anonymous):

It would help if you post the problem

geerky42 (geerky42):

since opposite of p is right angle, we can say that p is also right angle

OpenStudy (anonymous):

thats the problem what is the value of p

OpenStudy (wolf1728):

Thanks for the graphic.

geerky42 (geerky42):

you know that if triangle inscribed in circle contains one side that is also diameter of a circle, then it must be right angle triangle?

geerky42 (geerky42):

still confused?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

so do i have to like add or something

geerky42 (geerky42):

there is really no math involved, i mean take a look at diagram, you can split quadrilateral into two triangles. since side both triangle shares one sides, that is also diameter of a circle, then both must be right triangles.

geerky42 (geerky42):

does that make sense??

OpenStudy (anonymous):

so the answer would be 180

geerky42 (geerky42):

no, 90. what I'm saying is since the angle opposite of p is 90, p is also 90.

OpenStudy (anonymous):

ohh okay got it yeah i was confused

geerky42 (geerky42):

ya, you are welcome. :)

OpenStudy (anonymous):

OpenStudy (anonymous):
