You are calculating the perimeter of the triangle.
Just add up the 3 side lengths. It's 20.6 meters.
Answer:

Step-by-step explanation:
Parallel lines have the same slope. To find the slope, convert 3x-4y=7 into y=mx+b form.
3x - 4y = 7
-4y = 7 -3x
y= -7/4 + 3/4 x
The slope of the line is 3/4. Using this slope, substitute m=3/4 and the point (-4,-2) into the point slope form.

Use trigonometry:-
sin 26.5 = y / 15 (as sin = adj / hyp)
y = 15 sin 26.5 = 6.69 feet to nearest hundredth
