Answer:
B
Step-by-step explanation:
If A = {1, 2, 3} and B = {1, 2, 3, 4, 5}
We say that A is a subset of B, since every element of A is also in B.
So
If set A is all odd numbers then R belongs to A bcz all the elements of R are odd numbers
Answer:
84 cm^2
Step-by-step explanation:
The area of a triangle is calculated using the following formula:
1/2 * b*h <em>(b: base, h: height)</em>
1/2 * 14 * 12 = 84 the area is indicated with cm^2 so the answer is 84 cm^2
Answer:
107.25cm²
Step-by-step explanation:
Area of triangle = 0.5 * base * height
Base = 14.3 cm
Height = 15 cm
Hence, Area of triangle :
Area = 0.5 * 14.3 * 15
Area = 107.25cm²
Step-by-step explanation:
1. Choose arbitrary points A and B in the plane and draw segment AB.
2. Raise a perpendicular m to AB at A.
3. Raise a perpendicular n to AB at B.
4. Choose an arbitrary point C on line n.
5. Drop a perpendicular from point C to line m. Let D be the foot of this perpendicular.
6. Then quadrilateral ABCD is a rectangle.
