Answer:
38°
Step-by-step explanation:
The angle 1 is 63°
The angle 2 is the same of angle 1
so :
63°+79°=142°
then :
180° - 142° = 38°.
It's just telling you to multiple like 9×1=9 9×2=18 and so on.
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
Answer:
I really don't get what you're asking but in finding the new area 20 feet and 10 feet I found the area and the perimeter 14 cm2. I have found both perimeter and area so if you wanted an answer I guess it is in one of my answers.
