Answer:
x = 35°
Step-by-step explanation:
assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °
i.e.
40 + (2x+30) + 40 = 180
40 + 2x+30 + 40 = 180
110 + 2x = 180 (subtract 110 from both sides)
2x = 180 - 110
2x = 70
x = 35
Answer:
The length of line segment is 5
Step-by-step explanation:
we are given equation of parabolas as


Firstly, we will find intersection points
we can set them equal
and then we can solve for x

Multiply all sides by 8



now, we can factor it



now, we can find y-values
At x=-1:

y=2
so, we get point as
(-1,2)
At x=3:

y=-1
so, we get point as
(3,-1)
now, we can find distance between these two points
(-1,2)
x1=-1 , y1=2
(3,-1)
x2=3 , y2=-1
now, we can find distance

now, we can plug values


So,
The length of line segment is 5
