Answer:
b, c
Step-by-step explanation:
Reflection across a line is a "rigid" transformation, so linear measures and angle measures remain unchanged. (b and c are true statements)
Reflection across a line skew to the y-axis will mean that any segment originally perpendicular to the y-axis will not be after the reflection. ('a' is not a true statement)
Answer:
The angles are 22.5 and 67.5.
Step-by-step explanation:
A complement is the angle that when added to the given angle gives 90 degrees.
Therefore, the angle x is 3 times larger than its complement.
This means that x is 3/4 of 90 degrees and complement is 1/4 of 90 degrees.
Therefore, the angles are 22.5 and 67.5.

Answer:

Step-by-step explanation:
In order to find the side mentioned (IJ), we need to use SOH CAH TOA.
SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:
Sin = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tan = Opposite / Adjacent
Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.
Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.
Our equation is now this: 
Let's now solve for x.
Therefore, the length of IJ will be around 2.01.
Hope this helped!
The greatest common factor (GCF) of 35, 38, and 42 is 1.
There are no common prime numbers, so the GCF is 1.
