Find RST
To do this, we use:
--- angle on a straight line
Make RST the subject


<em>Hence, the measure of RST is 144</em>
Answer:
A
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 100 = 256
a^2 = 156
a = 12.48
a = 12.5
The figure shows two intersecting chord, thus this simply can be solved using the Intersecting Chord Theorem, which states that "<span>When two chords intersect each other inside a circle, the products of their segments are equal."
Thus,
(5mxn=15mx2m)
n=6m</span>
Given that the size of the buttons are:
1/8 inch, 3/8 inch and 1/4 inch
To compare the lengths we first convert the fractions into decimals for easy comparison.
To convert fractions into decimals we divide the numerator by the denominator:
1/8=0.125
3/8=0.375
1/3=0.25
from the above decimals we can see that 0.125 is the smallest and hence we conclude that the smallest button is 1/8 inches. The largest button is 3/8 inches.
