<span>Hi! All you need to know is that cot stands for cotangent and its the reciprocal of tan i.e. cot(x) = 1/tan(x). You probably know that tan(pi/4) = 1 and that tan(3pi/4) = -1. Happily in these cases it means that cot and tan come out the same (1/1 = 1 and 1/-1 = -1).
-1 - (+1) = -2 and this divided by pi/2 = -2/(pi/2) which looks a bit untidy so multiply the top and bottom by 2 (to get rid of the 2 in pi/2) and the answer is -4/pi. HTH</span>
Answer:
P=a+b+c
Step-by-step explanation:
a=side
b=base
c=side
in your case do this for each two lines on every angle and use base for the shape inside hope this helps
6x + 8 = 50
Our goal is to get the variable x on its own.
We can start by subtracting 8 from each side. (subtraction prop. of eq. lets us do this)
6x + 8 - 8 = 50 - 8
6x = 42
Now, we must divide each side by 6 to find the value of x.
6x ÷ 6 = 42 ÷ 6
x = 7
