Step-by-step explanation:
it is from minus infinity to infinity
It means find the angle whose tangent equals - sqrt (3)
the negative square root of 3 =

Looking up the arc tan </span></span><span>(-1.7320508076</span> ) on this page:

we find it equals -60 degrees
-5 = n + 1
Subtract 1 from both sides.
n = -6
-6 = x + 2
Subtract 2 from both sides.
x = -8
y - 9 = -2
Add 9 to both sides.
y = 7
x - 4 = -10
Add 4 to both sides.
x = -6
Answer:
115
Step-by-step explanation:
Perimeter = add all sides
15 + 20 + 30 + 50 =115
Hope this helps
