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°

Answer:
The equation of the line with slope = 4 and point (-5, -13)
will be:
Step-by-step explanation:
Given
- slope = m = 4
- point = (-5, -13)
As the point-slope form of the equation of line is
where m is the slope.
substituting the values m = 4 and the point (-5, -13)
subtract 13 from both sides
Therefore, the equation of the line with slope = 4 and point (-5, -13)
will be:
