4x+8y=40
0.8*8=6.4
4x+6.4=40
40-6.4=33.6
4x=33.6
33.6\4=8.4
X=8.4
Answer:
1. sometimes true
A rhombus is a quadrilateral with all equal size and length. A square is a quadrilateral with all equal size and length, and all right angles around bus, however, can be a square if it has right angles.
2. always true
A square has to have all equal sides and all right angles, however, a rectangle has to have right angles and opposite sides are equal to each other. So if a square has equal sides, it can be considered a rectangle since both opposite sides are equal
3. sometimes true
A parallelogram is a quad roulette or with parallel and equal opposite sides, and a rectangle has right angles and equal opposite sides, therefore, if the parallelogram has right angles, then it is considered a rectangle
4. always true
A quadrilateral has to have 4 sides and the rectangle has 4 sides there, for it is considered a quadrilateral
5. never true
A parallelogram is a quadrilateral, therefore, it has to have 4 sides, but a hexagon has to have 6 sides, therefore, it is never a hexagon
Answer:
length = 15
breadth = 25
Step-by-step explanation:
length = breadth + 10
let length be x
length = x
breadth = x + 10
perimeter = 2(length) + 2(breadth)
80 = 2(x) + 2(x + 10)
80 = 2x + 2x + 20
80 = 4x + 20
80 - 20 = 4x
60 = 4x
15 = x
length = x = 15
breadth = x + 10 = 25
Answer:
24°
Step-by-step explanation:
There are 360° in a rhombus, 180° in a triangle.
If 132° is taken up then that leaves 48° for a triangle, 96° for a rhombus.
Assuming that all of the remaining angles (<1,<2,<3, and <4) are equal, then dividing 48 by 2 or 96 by 4 gets you 24°
