Form a right angle triangle joining both given points to the origin, we get:
Perpendicular = 2 ( distance is always positive)
Base = 4 ( same logic)
Applying Pythagorus theorem
Hypotenuse = root of ( perpendicular squared + base squared)
Hypotenuse = root of 20 = 2 * root 5
Using x instead of theta
Sin x = perpendicular/hypotenuse
Cos x = base/hypotenuse
Sin x = -1/ root 5
Cos x = -2/ root 5
High probability of this answer being wrong.
Double check recommended.
Answer:
-71
Step-by-step explanation:
First, note that
1 yard = 3 foot,
1 feet = 12 inches.
Now add all lengths:
15 ft 4 in + 9 ft 2 in + 14 ft 7 in + 10 ft 11 in +5 ft 8 in = 53 ft 32 in.
Since 32 in = 24 in + 8 in = 2 ft 8 in, then
53 ft 32 in = 53 ft + 2 ft 8 in =55 ft 8 in.
Since 55 ft = 54 ft + 1 ft = 18 yd 1 ft, then
55 ft 8 in = 18 yd 1 ft 8 in.
Answer: correct choice C
The answer is, x=11
hope this helps!
