Answer:
B
Step-by-step explanation:
Reflection is a transformation that preserves lengths.
Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.
This means that corresponding sides have the same lengths:
- XY = X'Y' = 7 in;
- XZ = X'Z' = 4 in;
- YZ = Y'Z' = 5 in.
Find the perimeters of both triangles:
Hence, only option B is true.
Answer:
50° & 90°
Step-by-step explanation:
it's a right angle triangles, so one must be 90°
Interior angles in a triangle add up to 180.
180 - 90 - 40 = 50°
Yes, it is a linear equation.
To answer this question let us first define what a rational and irrational number is. A rational number is basically a number whose decimals are terminating (ie have an end) or repeating (continuously repeats the same pattern.
An example of this from your question would be
5.3 - terminating rational number
5.333333333333..... - repeating rational number
Irrational numbers are basically numbers whose decimals are non terminating and non repeating.
An example would be the square root of 29. When plugged in a calculator this would result in <span>5.3851648071.....
</span>This number goes on and on with no set pattern.
