The two points are on the same line on the x-axis, so to find the length we need to find the distance between the points on the y-axis. Subtract one y from the other (it doesn't matter which) and take the absolute value. 18 - (-7) = 25. The absolute value of 25 is 25. The length of that side of the rectangle is 25.
RS is the length of segment RS, not the length of arc RS.
ST is the length of segment ST, not arc ST.
The arcs RS and ST have little marks in the picture. These marks indicate that the arcs are congruent. They have the same length. In a circle, or in congruent circles, congruent arcs are intercepted by congruent chords.
This means that segments RS and ST are congruent.
ST = RS
10x - 31 = 59
10x = 90
x = 9
Answer:
x= 15 and y=4
Step-by-step explanation:
Let's start by finding y first using the basic proportionality
= 
- 12*6 = 18y
- 72 = 18y
- y = 72/18
- y= 4
now time to find x using the same way:
=
