in point a on the cirlce, angle CAD=3x+9 and angle FAB=2x+21 given that EC and DF are diameters what is the measure of FAB

Question

This question is asking about a circle and it is hard i need some help now

Answer 1

Sydney,

 

These are congruent angles between EC and DF so angle CAD equals angle FAB. Solve for x and then multiply out to find angles FAB and CAD.

 

Hope that helps,

Answer 2

May not be enough info to help you with this problem. Need to know where point B is in relation to all other points, unless you meant to type in angle FAE instead of FAB.

If that's what you meant, then the measure of angle CAD = measure of angle FAE. 

2x+21=3x+9, then solve for x.

Plug that value into equation to find measure of angle FAE.
