The sum of all the angles of a triangle is 180 degrees.
If you add 90 + 90 + 90 together you get 270. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.
If you add 80 + 80 + 200 together you get 360. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.
If you add 40 + 50 + 60 together you get 150. These can not be the angle measures of interior angles of a triangle because the sum is less then 180.
If you add 15 +30 + 135 together you get 180! This set of angle measures can the be interior angles of a triangle!
Hope this helped!

Answer:
6300
Step-by-step explanation:
To find the area of a parallelogram, you simply have to multiply the base and the height. The formula is "A = bh." So, multiply 8 and 4, and you'll get 32. The area of this parallelogram is 32ft.
From the following figure:
Because the center angle measure 45 degrees, we must rotate 3 times 45 degrees to get point D.
In other words, we must rotate

that is 135 degrees clockwise.
