A very useful result called the inscribed angle theorem tells us that, given any <em>inscribed angle</em> on a circle (an angle on the inside edge of a circle) the <em>central angle </em>that <em>subtends the same arc</em> is <em>twice the measure of the inscribed angle</em>. I've included a visual example for this problem if any of that vocabulary is unfamiliar.
Here, the inscribed angle ∠C = 87° is attached to the arc DEB. According to the inscribed angle theorem, the central angle swept out by DEB should then be 87 x 2 = 174°. To find the measure of arc DE, we note that arc DEB is just arc DE + arc EB. We're given that arc EB measures 76°, so we subtract that from 174 to find that arc DE = 174 - 76 = 98°
Answer:
(4.449, 0.449) and (-0.449, -4.449)
Step-by-step explanation:
xy = 2
y =
Vertical asymptote → x = 0
Horizontal asymptote → y = 0
Input-output values for the equation,
x -2 -1 1 2 4
y -1 -2 2 1 0.5
Input-output values of the equation,
x - y = 4
x -2 -1 0 1 2
y -6 -5 -4 -3 -2
Solutions of the system of equations → (4.449, 0.449) and (-0.449, -4.449)
