Answer:
X=50°
Step-by-step explanation:
Let, the fourth angle in the quadrilateral be ∠A
The sum of all the four angles of the quadrilateral is 360°
So 40° + 110°+80°+∠A=360°
230°+∠A=360°
∠A=360°-230°
∠A=130°
The fourth angle of the quadrilateral is 130°
The angle A and X are the angles on a straight line
The sum of the angles on a straight line is 180°
so, ∠A+∠X=180°
130°+∠X=180°
∠X=180°-130°
X=50°
1:4 is equal to 2:8, it's a simplified version.
For this case we have that by definition, the slope of a line is given by:
Where:
and
are two points through which the line passes.
According to the figure we have to, the line goes through:
Substituting we have:
Thus, the slope of the line is -1.
Answer:
