Answer:
The answer to your question is 7 and -1/7
Step-by-step explanation:
Data
First line Second line
B (4, 4) A (0, 1)
M (3.5, 0.5) C (7, 0)
Formula
Slope = m = (y2 - y1) / (x2 - x1)
Process
1.- Calculate the slope of the first-line
x1 = 4 y1 = 4
x2 = 3.5 y2 = 0.5
-Substitution
m = (0.5 - 4) / (3.5 - 4)
-Simplification
m = -3.5 / -0.5
-Result
m = 7
2.- Calculate the slope of the second line
x1 = 0 y1 = 1
x2 = 7 y2 = 0
-Substitution
m = (0 - 1) / (7 - 0)
-Simplification
m = -1/7
-Result
m = -1/7
X = 21 + 34
Answer: x = 55°
