Answer:
t = 9.57
Step-by-step explanation:
We can use trig functions to solve for the t
Recall the 3 main trig ratios 
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse 
Tan = opposite / adjacent. 
( note hypotenuse = longest side , opposite = side opposite of angle and adjacent = other side ) 
We are given an angle as well as its opposite side length ( which has a measure of 18 ) and we need to find its adjacent "t" 
When dealing with the opposite and adjacent we use trig ratio tan. 
Tan = opp / adj
angle measure = 62 , opposite side length = 18 and adjacent = t
Tan(62) = 18/t
we now solve for t 
Tan(62) = 18/t 
multiply both sides by t
Tan(62)t = 18
divide both sides by tan(62)
t = 18/tan(62) 
t = 9.57
And we are done!

The length of the sides are 2.24, 4.24 and 4.12 units while the slope are 0.5, -1 and -4.
<h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
For RS:
For RT:
For ST:
The length of the sides are 2.24, 4.24 and 4.12 units while the slope are 0.5, -1 and -4.
