In the given figure, find m∠RST, if m∠RSU = 43º and m∠UST = 23º.
pickupchik [31]

Applying the angle addition postulate, the measure of angle RST is: 66°.

<h3>What is the Angle Addition Postulate?</h3>

If two angles share a common vertex and a common side, they are adjacent angles that form a larger angle. According to the angle addition postulate, the sum of these two adjacent angles will give a sum that is equal to the measure of the larger angle they both form.

We know the following:

Measure of angle RSU = 43º

Measure of angle UST = 23º

In the diagram given, angle RSU and angle UST are adjacent angles that form a larger angle, angle RST.

Therefore, based on the angle addition postulate, the measure of angle RST = sum of the measures of angles RSU and UST.

Therefore, we would have:

m∠RST = m∠RSU + m∠UST

Substitute

m∠RST = 43 + 23

m∠RST = 66°

1. If you were to describe a TRANSLATION of triangle ABC, what information would you need to include in your description?
cluponka [151]
A translation is when a triangle moves from one location to another while staying the same size/position.

A rotation is when it changes positions, like it can turn upside down or to the side.

A reflection is when it translates over the x or y axis.

Please help, I have no idea.
svp [43]
Option 1. Incorrect because if 0 is added to 4 and then 2 is subtracted, it will not greater or equal to 6
option 2. Correct because if 4 or is added to negative 12 or less and then turned into the absolute value and the 2 is subtracted then it will be greater than 6. if there is 4 or more that also works, because 4 plus 4 is 8 and the subtracted 2 is six, everything greater is also valid so option to is the correct answer
