Question

How would I do this problem? Find the value of x for the measure of arc AB = 27 degrees and the measure of arc CD = 49 degrees.

Answer 1

join AD

Answer 2

in \(\triangle OAD\) find the angles \(\angle A\) and \(\angle D\)

Answer 3

\(x = \angle A + \angle D\)

Answer 4

Is it 51.5?

Answer 5

what did u get for \(\angle A\) and \(\angle D\) ?

Answer 6

i did the process incorrectly, im going to try again

Answer 7

What is the first step for how I supposed to find x? I need to make sure I am doing this right.

Answer 8

good :)

first step : join AD

Answer 9

Okay

Answer 10

Next, look at \(\triangle OAD\)

Answer 11

Okay

Answer 12

\(\angle A = CD/2 \) (why ?)

Answer 13

\(\angle A = CD/2\)
= \(49/2\)

Answer 14

And then angle D would be = AB/2 right?

Answer 15

thats correct :)

Answer 16

So it is 38 :) Thanks!!!

Answer 17

wow ! you're awesome !!! good work :)
