Answer;
-Calculate the lengths of the diagonals, and show that they are equal.
-Calculate the slopes of every side, and show that adjacent sides are perpendicular.
Explanation;
-A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. If the diagonals of a parallelogram are congruent, then it’s a rectangle and also if a parallelogram contains a right angle, then it’s a rectangle.
Answer: The answer would be c
Step-by-step explanation:
Step 1: Solve for b
5a+b=7
b=-5a+7
your slope would be -5a
Step 2: Make it perpendicular
The Perpendicular is gonna be the opposite
So it would be b= 1/5+7
The slopes has to be different and you don't have to worry about the "+7"
Reply if you have any questions
14/38 simplified would be 7/19
Answer:
which would be 1 third times 3.14 times 6 squared times 33
Step-by-step explanation:
okay so your dealing with a cone and a hemisphere. so what you would do is the cone equation is 
multiplied by 
multiplied by the radius squared times the height so what u would o is plug in the things you know .
Answer:
C. AAS
Step-by-step explanation:
they share 2 angles(A) you can tell by the markings and they share that one side
by this point you have 2 options left
ASA
or
AAS
the angles are right next to each other so it's AAS
