Answer:
b. 63
Step-by-step explanation:
A Parallelogram is known to be a flat shape quadrilateral which has four opposite sides Each two opposite sides are parallel and are equal in length. The opposite angles are equal.
The above answer is correct because opposite angles of a parallelogram are equal:
m∠CDA = m∠ABC
where m∠CDA = 63
∴ m∠ABC = 63 (answer)
Answer:slope= 0.9 approximately
Step-by-step explanation:
Slope=y-y/x-x
=0-11/5-17
=11/12
=0.9 approximately to nearest one decimal
A = (Vf - Vi)/t
Multiply by t on both sides to clear the denominator
at = Vf - Vi
Add Vi to both sides.
at +Vi = Vf
The solving for the first one should be like this

And the next part

After these manipulations just multiply them

And finally you need to square and simplify for the completed answer
