Solution:
To find the equation of line passing through points A (1, 3) and B (3, 7).
we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points 
and 
is given by -

The expression to find the value of the final angle of the triangle will be 180° - 40° - α.
<h3>How to solve the triangle?</h3>
Your information is incomplete as the triangle isn't attached. Therefore, an overview will be given.
Firstly, it's important to know that the total angle in a triangle is 180°. A triangle has three sides. In this case, angle B is given as α.
Let's assume that another angle is given as 40°. Therefore, the expression to find the value of the final angle will be 180° - 40° - α

Answer:
The minus 3 in the square will shift the graph to the right 3 x-coordinates and the minus 8 in the outside will move the graph downwards by 8 y-coordinates.
Step-by-step explanation:
The minus 3 in the square will shift the graph to the right 3 x-coordinates and the minus 8 in the outside will move the graph downwards by 8 y-coordinates.
Answer:
A = 23°
b = 9.5
c = 14.7
Step-by-step explanation:
B = 32°
C = 125°
a = 7
✔️Find A:
A = 180° - (B + C) (sum of triangle)
A = 180° - (32° + 125°)
A = 23°
✔️Find b using Law of Sines:
Plug in the values
Cross multiply
Divide both sides by sin(23)
b = 9.5 (nearest tenth)
✔️Find c using Law of Sines:
Plug in the values
Cross multiply
Divide both sides by sin(23)
c = 14.7 (nearest tenth)
