Answer:
x = 75
Step-by-step explanation:
Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.
A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:
.
To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
Answer:
reflect over the x-axis
Step-by-step explanation:
Transformation is the movement of point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point A(x, y) is rotated 180° clockwise about the origin the new position would be A'(-x, -y)
If a point A(x, y) is reflected over the y-axis the new position would be A'(-x, y).
If a point A(x, y) is reflected over the x-axis the new position would be A'(x, -y)
If a point A(x, y) is translated a units left the new position would be A'(x-a, y).
The rectangle has points at (2, 2), (2, 5), (7,2), (7,5). If the rectangle is reflected over the x-axis the new position would be at (2, -2), (2, -5), (7, -2), (7, -5) which is at the fourth quadrant
