Answer:
perimeter=40.9ft
Step-by-step explanation:
The length at the top is 10ft,the length at the bottom is 10+4ft=14ft and the other lengths are8.9ft and 8ft
perimeter=10+14+8+8.9=40.9ft
Since this is a quadrilateral, all angles together = 360°. The angle that is 128° is congruent to angle y, so y=128°. Angle x and y are supplementary, meaning together they equal 180°, or x+y=180°. So x=180°-y. Which means, x=180°-128°=52°.
Answer:
10
Step-by-step explanation:
6-(-4)=10
I think so lol
Hello! -1 - 9 is -10. F = -10. 7 - 9 is -2. G = -2.
F = -10
G = -2
d = 3
Okay, so because d and F are beside each other, we multiply both of the values. Let's plug in the values. -10 * 3 is -30. This is because one negative and one postive make a negative number. Now, we add the number. Because it is negative, we have to go into the negatives more. -30 + (-2) is -32. There. The answer is -32.
Answer:
36
Step-by-step explanation:
split it into half, and you'll see that each rectangle when split into half has 2 triangles that are 12 ft, and now AECD is 3 lots of those 12 triangles that is 12 feet in area, therefore total would be 12 x 3 = 36
