Quadrilateral KLMN is rotated clockwise 90 degrees?
Answer:
407.22 foot is the boat from the base of the lighthouse
Step-by-step explanation:
Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.
Let x foot be the distance of the object(boat) from the base of the lighthouse
Angle of depression =
[Alternate angle]
In triangle CAB:
To find AB = x foot.
Using tangent ratio:
Here, BC = 50 foot and
then;
or
Simplify:
AB = x = 407.217321 foot
Therefore, the boat from the base of the light house is, 407.22'
18000 divided by 360, then multiply that new number with 48. i believe that is the correct math...<span />
Answer:
Step-by-step explanation:
1) 5 + 12 + 2 + 15 + 9 /5
= 43/5
= 8.6 years
2) 8 + 12 + 7 + 10 + 15 / 5
= 52/5
= 10.4 points
3) 144 + 270 + 204 / 3
= 348 + 270 / 3
= 618 / 3
= 206 books
Answer:
6
Step by step explanation:
2 + 2 * x = 10
2x+2=10
2x+2−2=10−2
Therefore, x = 6
