Question

If the radii of the circles are 5 and 3, the ccenters are A and b and both angle owlet and angle DBC are right angles, what is the perimeter of triangle CEG?
(a) 32
(b) 16 + 16 square root 2
(c) 30
(d) 16 + 10 square root 2
(e) can't be determined

Answer 1

in the small triangles, the angles that are not 90 degrees are 45 degrees.
If you drop a line from point E, by similar triangles you will find that the two angles that add to give angle GEC are also 45, so GEC is 90.

Answer 2

The combined diameters are 16.

Answer 3

I believe that should give you enough to solve the problem.

Answer 4

i got (b) 16 + 16 square root 2

Answer 5

thanks

Answer 6

That is what I got too.
