Answer:
Twelve-fifths.
Step-by-step explanation:
The diagram is shown below
Given triangle be right angled at ,
Withe reference to ,
Its opposite side is , adjacent side is and hypotenuse is
We are to find the value of
We know
Substituting the above values we get,
So the answer is Twelve-fifths.
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
1.80 divided by 7 would give you .257 but if you round it, it's.26
