Question

Geometry Help Please!

Answer 1

@SolomonZelman, could you help please?

Answer 2

the equation of a circle centre (a,b) with radius r is

(x-a)^2+(y-b)2 = r^2

you know a, b and r from the question - so plug them into that equation for the answer

Answer 3

no - the answer will still have x and y in it

the values of a and b are the centre of thecircle (th e5^2 bit IS correct)

(x- xcentre)^ 2 (y- ycentre)^2 = 5^2

Answer 4

Opposite pairs of angles in the inscribed quadrilateral add up to 180

so use the pair that you DO know to work out x

then use that value of x in the OTHER pair of angles to calculate the missing angle

Answer 5

I'm still confused in the second one...

Answer 6

you know the 2 expressions for the angle at O and Q (in terms of x

so add them together - you will then have an equation

blah x blah + something = 180

this is a simple linear equaiotn in x - so you can get the vaule for x


I made a mistake above - ROP is the answer

once you have x you know ROP = x+17
