Answer:
the ship is at a distance of 60 feet
Step-by-step explanation:
we have to think of the problem as a right triangle, since
we have 2 legs and 1 hypotenuse, we know the measure of the leg that gives us the height and the angle that that leg touches
the leg we want to calculate is the opposite of the angle we have, since it does not touch
well to start we have to know the relationship between angles, legs and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, adjacent, opposite)
is the tangent
tan α = o/a
tan 22 = o/150
tan 22 * 150 = o
60.6ft = o
round to the nearest foot
60ft
the ship is at a distance of 60 feet
Answer: -4 <= x < 4. For the second answer, it’s -2 <= y < 5
Step-by-step explanation:
Answer:
6 cms.
Step-by-step explanation:
If the side of an equilateral triangle is 2x cm then its height is √3x and its base is 2x.
Area = 1/2 * base * height
9√3 = 1/2 * 2x * √3x
9√3 = x * √3x
9 = x^2
x = 3
So length of each side = 2*3 = 6.
x = 9
<span>Equation:
0.15x + 0.10(5-x) = 0.11*5
---
Multiply thru by 100:
15x + 10*5 - 10x = 11*5
---
5x = 5
x = 1 liter (amt. 15% oj needed)
----
5-x = 4 liters (amt of 10% oj needed)

Answer:
Infinite amount of solutions.
Step-by-step explanation:
Note that both sides of the equation is -3x. This means that regardless of what you put into x. It will always be the same on both sides.
