Answer:
Option B
Step-by-step explanation:
The slope of the line BC is,
Since AD is altitude to BC, we can say AD is perpendicular to BC, so the slope of the line AD which is perpendicular line to BC will be,
Answer: b
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
x + 107 = 180
x + 107 - 107 = 180 - 107
x = 73
The correct answer is B. 73 degrees.
Hope this helps =)
