Answer:
17.94
Step-by-step explanation:
The formula for a problem like this is
P W/2 -W^2
Multiply the perimeter by half of the width and then subtract the width squared.
7.8/2 This would give us 3.9
Then we multiply this by the perimeter
3.9x20.2 This leads us too 78.78
Then we subtract w^2
7.8X7.8 Is equal too 60.84
Then we subtract
78.78-60.84 This leads us too 17.94
Answer:
4
Step-by-step explanation:
Assuming the points are on a line in the order F, G, H, I, then segment addition tells you ...
... FG + GH + HI = FI
... 2 + GH + 1 = 7
... GH = 7 - 2 - 1
... GH = 4
Hello there, and thank you for posting your question here on brainly.
A trapezoid is not possible to have for obtuse because it would look more like a diamond. Also, if it had 4 obtuse angles, it would have 6 sides.
Hope this helped!! ☺♥
