Supplementary angles is when 2 angles add up to 180 degrees.
We will name the smaller angle a and the bigger angle b.
therefore:
b - 172.6 = a
a + b = 180
Now we substitute:
a + b = 180
b - 172.6 + b = 180
2b - 172.6 = 180
2b = 352.6
b = 176.3
To find a:
a + b = 180
a + 176.3 = 180
a = 3.7
Therefore,
angle a = 3.7 degrees
angle b = 176.3 degrees.
Hope it helps and have a great day ahead

The point B is located at (-6.5, 0)
<h3>How to determine where is point B located?</h3>
The points are given as:
A = (1/2, 6)
Center = (-3, 3)
The center is calculated as:
Center = 0.5 * (x1 + x2, y1 + y2)
So, we have:
(-3, 3) = 0.5 * (1/2 + x, 6 + y)
This gives
(-6, 6) = (1/2 + x, 6 + y)
Solve for x and y
1/2 + x = -6
6 + y = 6
This gives
x = -6.5
y = 0
Hence, the point B is located at (-6.5, 0)

Answer:
(2, 22 )
Step-by-step explanation:
Given the 2 equations
y = 7x + 8 → (1)
y = x + 20 → (2)
Substitute y = 7x + 8 into (2)
7x + 8 = x + 20 ( subtract x from both sides )
6x + 8 = 20 ( subtract 8 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Substitute x = 2 in (2) for corresponding value of y
y = x + 20 = 2 + 20 = 22
Solution is (2, 22 )
