In the diagram shown, chords ab and cd intersect at e. the measure of (ac) ̂ is 134°, the measure of (db) ̂ is (3x)° and the measure of ∠aec is (7x)°. what is the degree measure of ∠ aed?

The measure of angle AED is

Step-by-step explanation:

step 1

Find the measure of x

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite

In this problem

m<AEC is a interior angle

so

substitute the values and solve for x

step 2  

Find the measure of angle AED

we know that

-----> by supplementary angles

Convert to mixed number
