QUICK ANSWER
A quadrilateral with exactly one pair of opposite parallel sides is called a trapezoid. As with all quadrilaterals, the sum of the interior angles of a trapezoid is always equal to 360 degrees
We have the equation 1/2x + 200 =1200 so we know that we have 200 already as one of the numbers so 1/2 is half of x + 200 equals 1200 since we have 200 we know that 1/2 of x is going to be 1000 because 1000+200=1200 meaning x is 2000. So your answer would be x=2000 or 1/2 2000 + 200=1200
Answer:
y - 1 = - (x - 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (- 2, 5)
m =
=
= - 1
Using (a, b) = (2, 1), then
y - 1 = - 1(x - 2), that is
y - 1 = - (x - 2)
The value of X would be _#_##_#_#_#_#_##_#_#_#
Answer:
it's angle 1.
Reason:
vertically opposite angles are equal
