Answer:
I think its option D.d=5
Step-by-step explanation:
After writing the question rearrange into same sides
d-2d-d+3d=8-10+10-7
d-d-2d+3d=12-7
-2d+3d=5
d=5
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.
<h3>What is
trigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of right angled triangle.
Let d represent the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:
Angle = 90 - 67 = 23°
Using trig ratio:
tan(23) = d/1143
d = 485.2 feet
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.

Answer:
C
Step-by-step explanation:
Two negatives cancel out and turn into a positive.
In the expression 11 - ( -3 5/8 ) there are two negative signs. If the parenthesis are removed, the two negative signs cancel out and turn into a positive and we are left with 11 +3 5/8
So the answer is C
Hey there! :)
The formula for finding volume of a cone : ( π · r² · h ) ÷ 3
Radius = 6
6² = 6 · 6 = 36
Height = 8
π = 3.14
Multiply:
8 × 6 × 3.14 = 150.72
The volume is 150.72 cubic meters
Hope this helps :)
