Question

If MAC 109 and MBD = 29°, what is m∠BED? 80° 40° 69° 35°

Answer 1

check the picture below.

Answer 2

B) 40°

Explanation:

Given: m∠AC = 109° and m∠BD = 29°

We need to find m∠BED.

Here we have to use the following formula.

m∠BED =
`(Major arc - minor arc)/(2)`

Here the major arc is m∠AC = 109° and the minor arc is m∠BD = 29°

Plug in these values in the above formula, we get

m∠BED = (109° - 29°)/2

= 80°/2

m∠BED = 40°

The answer is B) 40°
