Answer:
EC = 35
Step-by-step explanation:
The whole entire line measures 49
DB measures 30
49 - 30 = 19 or ED

Answer:
2.4x+15.2
Step-by-step explanation:
Answer:
40°, 95°, 105°, and 160°
Step-by-step explanation:
Let the smallest angle be x.
Measures of the 3 angles can be expressed as:



The sum of all angles in a quadrilateral = 360°.
Therefore, 
Solve for x






The smallest angle = 40°
Plug in the value of x in the earlier stated expressions to find the measure of the other angles:



Parallel lines have equal slopes, so if green line has slope = -2 then, red line's slope would be equal to -2
In short, Your Answer would be Option A
Hope this helps!
