Part 1) The measure of arc AB is 50°

Part 2) The measure of angle AOB is 50°

Part 3) The measure of angle BDA is 25°

Step-by-step explanation:

step 1

Find the measure of arc AB

we know that

arc AD+arc BD+arc AB=360° > by complete circle

substitute the given values

212°+98°+arc AB=360°

310°+arc AB=360°

arc AB=360°-310°=50°

step 2

Find the measure of angle AOB

we know that

The measure of angle AOB is the same that the measure of arc AB by central angle

so

m∠AOB=arc AB=50°

step 3

Find the measure of angle BDA

we know that

The inscribed angle measures half that of the arc comprising

so

m∠BDA=(1/2)[arc AB]

we have

arc AB=50°

substitute

m∠BDA=(1/2)[50°]=25°

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
