1 answer:
Reflecting the polygon FGHI across the line involves flipping the line across the line y = -1
<h3>How to reflect the polygon?</h3>The coordinates are given as:
F(2, – 1), G(5,2), H(8, 3), and I(6, 0)
The line of reflection is given as:
y = -1
To reflect the line, we apply the following rule of reflection
(x,y) (x,-y-2)
So, we have the following coordinates of the image
F' = (2, – 1)
G' = (5,-4)
H' = (8, -5)
I' = (6, -2)
See attachment for the image of the reflected polygon

If the value of x is 10. Then the measure of angle ∠COB will be 56°.
<h3>What is an angle?</h3>The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
Given that A, O, and B lie on a straight line segment.
Then they make a linear angle that is 180 degrees.
Then we have
∠AOC + ∠COD + ∠DOB = 180
(3x + 94) + (x + 30) + (2x - 4) = 180
6x + 120 = 180
6x = 60
x = 10
Then the measure of angle ∠COB will be
∠COB = ∠COD + ∠DOB
∠COB = (x + 30) + (2x - 4)
∠COB = (10 + 30) + (20 - 4)
∠COB = 40 + 16
∠COB = 56°
