Answer:
x = 50.5°
Step-by-step explanation:
Use SOH CAH TOA... Since the adjacent and hypotenuse are given, you must use cosine.
cos(x) = 14/22
cos^-1 (14/22) = 50.5°
Answer:
Step-by-step explanation:
In the figure attached to this solution a right angled triangle is formed with height as tent pole (9 feet), base as distance of rope pegged into ground from tent pole (7 feet) and hypotenuse as the guy's rope.
According to Pythagoras theorem :
H : Hypotenuse (here guy's rope)
B : Base (here distance of rope pegged into ground from tent pole = 7 feet)
P : Perpendicular (here tent pole = 9 feet)
#12:
Assuming that I have those points correct: (1, 5) and (-4, -10), the slope of this line is
5-(-10)
m = --------------- = 15/5 = 3
1-(-4)
The line passes thru the origin, so the y-intercept is 0.
So the equation of this line is y = 3x.
I see no marks (points) in the illustration for #13.
