X=28 that’s what it is in a verbal expression
Answer:
1) 5°: 5 is halfway from 0 and 10
2) 5°: 5 is halfway through -5 and 15
3)-5°: -5 is halfway through 5 and -15
4)0°: 0 is halfway through -8 and 8
Answer:
same
Step-by-step explanation:
Given:
Quadrilateral PQRS
P(o, o), Q(a+c, o), R(2a+c, b), S(a, b)
Find:
whether the diagonals are perpendicular using coordinate geometry
Solution:
If the diagonals are perpendicular, their slopes multiply to give -1.
The slope of PR is
(b-o)/(2a+c-o)
The slope of QS is
(b-o)/(a-(a+c)) = (b-o)/(-c)
The product of these slopes is
(b-o)·(b-o)/((2a+c-o)(-c))
This value will not be -1 except for very specific values of a, b, c, and o.
It cannot be concluded that the diagonals of PQRS are perpendicular based on the given coordinates.
x+4=3x
first subtract x from both sides(x-x and 3x-x)
4=2x
Now divide 2 from both sides (2x/2 and 4/2)
2=x
So x=2
