Answer:
Angle CDE equals 155 degrees :D
Step-by-step explanation:
parallel lines
since the left angle is 57, angle BAE is also 57
180-57=123
right angle=90
115+90+123+57=385
540-385=155
thus, angle CDE equals 155 degrees
Answer:
The correct option is 1.
Step-by-step explanation:
If a quadratic equation is defined as
.... (1)
Then the sum of the roots is -b/a and the product of roots is c/a.
The given equation is
... (2)
From (1) and (2) we get a=3, b=11 and c=-4.
The sum of roots is

The sum of roots is
.
Therefore the correct option is 1.
