Hey!
----------------------------------------------------------------
We Know:
m∠AED = 34°
m∠EAD = 112°
----------------------------------------------------------------
Solution:
You notice 4 small triangles in both triangles. That shows that both triangles are the same.
The angles are the same for m∠BDC and m∠AED.
The angles are the same for m∠ADB and m∠EAD
----------------------------------------------------------------
Angles:
m∠BDC = 34°
m∠ADB = 112°
----------------------------------------------------------------
Congruent Angles:
m∠AED ≡ m∠BDC
m∠EAD ≡ m∠ADB
----------------------------------------------------------------
Hope This Helped! Good Luck!

Answer:
In Option A, we can see that the reverse may not be true as the increase in the risk for lung cancer may not necessarily mean an increase in cigarette smoked in a day. For example, high risk of lung cancer may be due to high exposure to asbestos dust too.
In Option B, again we can see that the reverse may not be true as an increase in the height of an infant does not necessarily mean that the age of the infant is increasing too. For example the infant may have a rapid gain in height even if the age is not increasing as rapidly.
In Option C, too, that an increase in the amount of pollution in a city does necessarily mean that the number of vehicles in the city has increased. For example, this increase in pollution may be due to the establishment of a high pollution causing industry in the city or in it's vicinity.
Likewise, in Option D, an increase in the density of water does not necessarily mean that the concentration of salt in the water has increased.
Only in Option E do we see a possible reverse dependence happening because an increase in the phone bill amount does usually mean an increase in the number of calls made by the cell phone.
So, in the given list of Options only in Option E can we reverse the dependent and independent variables while keeping the interpretation of the slope meaningful.

Answer: 16 rotations
Step-by-step explanation:
Given : Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his inline skates are 32 cm in circumference.
Length of ramp = 500 cm
Circumference of wheels = 32 cm
Formula :
Number of rotations = Length of ramp divided by Circumference of wheels
= 500 cm ÷ 32 cm
= 15.625 ≈ 16 [approx]
Therefore, each wheel makes 16 rotations while Shawn is coasting down the ramp.
Answer:
EF×AB= DF×AC
6×12=9×8
72=72
A is the correct answer also the angle in the diagram too.
