Answer:
=64 ft
Step-by-step explanation:
The wire, the pole and the flat surface form a right triangle with a base angle of 40°. The pole is the height of the triangle and is opposite the angle 40°.
Therefore we can use the trigonometric ratio -sine of the angle 40° -to find the height.
Sin∅ =opposite/hypotenuse
opposite=hypotenuse × sin∅
=100ft × Sin 40°
=64.28ft
≅64 ft

PEMDAS MATH
Answer:
x=7
Step-by-step explanation:
10+4x=5(x-6)+33
10+4x=5x-30+33
10+4x=5x+3
10=5x-4x+3
10=x+3
x=10-3
x=7
C becouse the premises aren't true
Answer:
60 ft
Step-by-step explanation:
Use Pythagorean theorem to solve this.
The pole = x
x^2 + 32^2 = 68^2
x^2 = 68^2 - 32^2
x^2 = 4624 - 1024
x^2 = 3600
x = 60
