Answer:
1) EA= 50 (because is a vertical angle with CB and vertical angles are congruent)
3) DEB = 210 ( to find AB subtract EA from 180, so 180-50 = 130. Then add together arcs DE, EA and AB to find the total measurement of DEB)
5) AB = 130 (I explain how to find it in question #3)
6) CDA = 180 ( To find CDA just add the measurements of CD, DE and EA together)
(sorry don't know the rest, hope this helps)
To solve this problem you must apply the proccedure shown below:
1.You have that the measure of the <span>leans a 4-foot and the angle between the bottom of the broom and the floor is 72°.
2. Then, you have:
Sin(72°)=x/4
When you solve for x, you obtain the following result:
4Sin(72°)=x
x=3.8 feet
The answer is: 3.8 feet</span>
7y+2(5y-9)=16
7y+10y-18=16
17y=34
y=2
5(2)-9=x
10-9=x
x=1
Neither because they are different size and mirrored it could’ve been congruent but it’s double the size and congruent is mirrored and the same size
