Answer:
Step-by-step explanation:
You have what is called "perfect squares" so you can use the "difference of squares formula to factor:
So,
you can work the equation backward now and you will get your original equation.
The time he spent running is 13.80 seconds.
<h3>
How much time did he spend running?</h3>
The equation that can be used to represent the time he gets to the tree is:
Time he gets to the tree = (time of each spin x total spins) + time he spent running
21 = (6 x 1.2) + r
21 = 7.20 + r
r = 21 - 7.20
r = 13.80 seconds

Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180. Thus, we have:
110+3s+8s=180
Simplifying, we have:
11s=70
Dividing by 11, we see that:
s=70/11
Therefore, RZS=3s=210/11, and TZS=8s=560/11.
