Question

What is the value of x? Show steps please!!

Answer 1

x = 8

Explanation:

Chords AB and BD form an inscribed angle so <ABD = 5x

also given mAD = 80

Since inscribed angles are half the measure of their intercepted arc, angle <ABD is equal to 1/2(80 degrees), which is 40 degrees.

Now you have:

<ABD = 40

5x = 40

x = 8

Answer

x = 8
