Answer:
84 degrees.
Step-by-step explanation:
First, let's define what a complementary angle is. It's when two angles add up to 90 degrees. So we do 90-6=84 and 84+6 does in fact equal 90, so they are complementary.
Answer:
8^2 = 64
unless you mean 8^2's square root then it is 8
Step-by-step explanation:
It wont be a perfect number
We are given an equation:
This is an equation of a circle. General form of a circle equation is:
Where:
a = x coordinate of a center
b = y coordinate of a center
r = radius of a circle
Motion detector can detect person anywhere within a boundary. The greatest distance at which detector can detect is at the edge of a circle. That distance, between detector and edge of circle, is equal to radius.
From the equation we have:
The greatest distance at which person can be detected is 4ft.
Answer:
194.
Step-by-step explanation:
x = (7+4√3)
x^2 = x = (7+4√3)^2
= 49 + 48 + 56√3
= 97 + 56√3
x^2 + 1/x^2 = 97 + 56√3 + 1/(97 + 56√3)
= 194.
