Suppose you're given 2 points: (a,b) and (c,d). The SLOPE of the line segment connecting these 2 points is given by
d-b
m=--------
c-a
Try this. Find the slope of the line segment connecting (3,4) and (7,9).
Answer:
2(+2)(+3)
Step-by-step explanation:
Answer:
x=6.5
Step-by-step explanation:
2x+3=16
2x=16-3
2x=13
x=13/2
x=6.5
So, we know that the internal angles of a triangle add up to 180 degrees, yes?
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.
Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!
Hope I helped!! :)
