Answer:
Step-by-step explanation:
A(-10,-3), B(7,14)
slope of AB = (-3-14)/(-10-7) = 1
slope of perpendicular to AB = -1
equation of perpendicular through C(5,12):
y-12 = -(x-5)
y-12 = -x+5
x = -y+17
x-intercept is the value of x when y=0.
x-intercept = 17
(0,17) is a point on CD.
Answer:
2-1/-2--4= 1/2
0-1/0-2=-1/-2
2-0/-1-0=2/-1
-2--1/4-2=-1/2
can i have a Brainliest plz thank you
Total distance = 1.6 miles
Madison has already hiked 0.4 miles
Miles left = 1.6 - 0.4 = 1.2 miles left
We will use the Pythagorean theorem:
c² = a² + b²
b² = c² - a²
x² = 20² - 12²
x² = 400 - 144
x² = 256
x = √256
x = 16
The pole B : 16 m + 5 m = 21 m
Answer: C ) 21 m
