Answer: A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Find:
You can see that vectors and This means that opposite sides are parallel and option B is false.
Find the lengths of all sides:
As you can see the lengths of opposite sides are equal, but all lengths are not equal. Therefore, the last option D is false.
Now check whether angles A and B are perpendicular:
The dot products are not equal to zero, then angles A and B are nor right. This means that option C is false and option A is correct (ABCD is a parallelogram with non-perpendicular adjacent sides
AKA your correct awnser choice is A :)✨
I think the truss is just one of those triangles whose sides are 3ft, 3ft, 3ft so its perimeter is
Answer: 9 feet
That is dependent because it is changing.independent stays the same
Answer:
A 40
Step-by-step explanation:
We can find angle K
J + K + L = 180 The angles of a triangle add to 180
50 + K + 90 =180
140 +K = 180
Subtract 140 from each side
140-140 + K = 180-140
K = 40
Since the triangles are congruent
J = P
K = N
L = M
We want to find N
K = N = 40
K = N
