A couple questions (angles, lengths + measures)
Hey! These two questions are stumping me... so I figured I'd come here for some help.
1.) Circle with centre O, CE tangent at D, ∠AOD= 100° , ∠BAD= 48°. Find and explain your answers.
Here's an image I drew up: http://i50.tinypic.com/eq44t4.png
And these are the things I need answers for:
2.) Circle with diameter TD and tangents AB, BC, and CA
AR= 5 cm
BS= 9 cm
CS= 17.5 cm
AC ┴ AB
Here's a drawing I did of it: http://i49.tinypic.com/2z86bk5.png
Find the numerical value of each of the following:
a) length of AT
b) measure of angle TRD
c) length of RT
d) measure of line segment TD
e) length of AB
Thank you SOO SOOOO much in advance! I REALLY appreciate it!
