Answer: 6.25
create a ratio of 2.5/2 = x/5 and solve for x. First multiple both sides by 10 so you get 12.5 = 2x. Then you get x = 6.25.
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:
PD is the answer
Step-by-step explanation:
(PA) (PC) = (PB) (PD)
First rearrange as:

Taking logs of both sides, we get:


x = 6.26.
