Answer: (5, 2)
We simply add up the corresponding coordinates. The x coordinates of the two vectors are 2 and 3. They add to 2+3 = 5
The y coordinates are -1 and 3. They add to -1+3 = 2
So overall,
(2,-1) + (3,3) = (2+3, -1+3) = (5,2)
is the answer
Any quadrilateral has sum of all angles equal 360⁰.
So,
m∠D+78+91+90=360
m∠D=360-(78+91+90)=101⁰
Answer is A.
Answer: finding volume is length times width times height and area is length times with so the ways they are the same are the fact that you do length times width for both and they fact that they are both solved through multiplication.
