Answer:
A
Step-by-step explanation:
Point R is (1, 5).
The transformation (<em>x</em> + 1, <em>y </em>- 1) denotes a translation of one unit to the right and one unit downwards.
Simply add one to the <em>x-</em>coordinate and subtract one to the <em>y-</em>coordinate of R. Hence:
Next, we want to dilate RUST by a scale factor of three. Since the dilation is centered on the origin, we can simply multiply each coordinate by three. This yields:
Our answer is A.
Answer:
Option C) supplementary
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If two angles are supplementary, then their sum is equal to 180 degrees
In this problem
The measure of angles are
60° and 120°
Their sum is equal to
60° + 120°=180°
therefore
The two angles are supplementary
