Answer:
Step-by-step explanation:
Actual value: 55 - 21 = 34; estimated value: 55 - 20 = 35.
The difference between the actual and the estimated values of 55 - 21 is 1:
35 - 34 = 1
Answer:
45
Step-by-step explanation:
105+30 = 135
180-135= 45

The coordinates of triangle A′B′C′ is A′(2, 1), B′(1, 2), C′(3, 2)
On plotting the coordinates on the graph, it is found :
Option A is the coordinates of a straight line.
Option C is the coordinates of a bigger triangle
Option D has a different shape.
Only option B fulfills the required condition of similar shape and scale factor of 0.5 .
Vertices of a triangular garden:
A(4,2)
B(2,4)
C(6,4)
Scale factor = 0.5
What are the coordinates?
- A coordinate system in geometry is a system that uses one or more numbers, or coordinates, to determine the position of points or other geometric elements on a manifold such as Euclidean space.
- Coordinates are numerical distances or angles that uniquely identify points on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ). Mathematicians, scientists, and engineers use a variety of coordinate schemes.

Answer:
A leg.
Step-by-step explanation:
The hypotenuse is always the side that is across from the corner. In this triangle, the hypotenuse is 14.
The perimeter of the parallelogram end is 2*(8 +5) = 26 cm. The product of that and the depth gives the lateral area.
The area of the parallelogram ends is 2*8*3, so the total area is
.. surface area = (26 cm)*(7 cm) +2*(8 cm)*(3 cm) = 230 cm^2
