Bracket expansion or simplifying
Answer:
perimeter of square = s+s+s+s
= 15+15+15+15
= 60 ft
The measure of the angle TRS is 34 degrees
<h3>Line and angles</h3>
The point where two lines meet is known as an angle
Given the following parameters
<QRS = 88 degrees
<QRT = 54 degrees
Using the expression
<QRS = <QRT + <TRS
Substitute the given parameters
88 = 54 + <TRS
<TRS = 88 - 54
<TRS = 34 degrees
Hence the measure of the angle TRS is 34 degrees
