The polygon is reflected across the line y = −7 and rotate 540° clockwise about (−7, 8). Then the correct option is C.
<h3>What is a transformation of a point?</h3>
A spatial transformation is each mapping of feature space to itself, and it maintains some spatial correlation between figures.
The polygon is given below.
The polygon is reflected across the line y = −7 and rotate 540° clockwise about (−7, 8).
Then the correct option is C.

The 2 triangles in the big triangle are similar so we can write
3x / 3x - 2 = 5x / 3x
9x^2 = 15x^2 - 10x
6x^2 - 10x = 0
x(6x - 10) = 0
x= 0 or 5/3
Answer:
110
Step-by-step explanation:
In the triangle angle theorem the angles will all add up to equal 180.
180-20-50=110
Answer:
688 cm²
Explanation:
Area of triangular prism = Base × Height + Length × (perimeter of base)
Here given:
- Perimeter of Base: (6 + 12.4 + 12.4) = 30.8 cm
============================================
Surface Area = 6 × 12 + 20 × (30.8) = 688 cm²
Answer: option c
length = 9m
Perimeter = 26.4m
Step-by-step explanation:
A rectangle has a width of 4.2 m and an area of 37.8 m^2
We want yo determine the length of the rectangle and the perimeter of the rectangle.
The perimeter of the rectangle is the distance round the shape. Let the width of the triangle be w.
The perimeter of the rectangle would be expressed as Length + width + length + width. This becomes
2(length +width). So the perimeter of the given rectangle is
2(length + 4.2) but the area is given as 37.8 m^2. Area of a rectangle is length × width. It becomes
37.8= length × 4.2
Length = 37.8/4.2 = 9m
Therefore, the perimeter is
2(length + 4.2) = 2(9+4.2)
Perimeter = 2× 13.2 = 26.4m
