20 points! these need to be answered today, so . this could make or break my grade. answer all 3. i only have one shot at this so make sure the answers are correct.

Question 1)

Question 2)

Question 4)

Step-by-step explanation:

Question 1) we know that

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

so

In this problem

substitute the values and solve for x

Question 2) we know that

The measurement of the external angle is the semi-difference of the arcs it comprises

so

in this problem

solve for x

Question 4) we know that

The measurement of the external angle is the semi-difference of the arcs it comprises

so

in this problem

solve for x

Find the measure of arc BD

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p
