Answer: i need more information in order to help
Answer:

Step-by-step explanation:
In order to find the side mentioned (IJ), we need to use SOH CAH TOA.
SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:
Sin = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tan = Opposite / Adjacent
Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.
Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.
Our equation is now this: 
Let's now solve for x.
Therefore, the length of IJ will be around 2.01.
Hope this helped!
Using the slope concept, it is found that the angle between the ladder and the floor will be of 33.69º.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem, we have that:
- The vertical distance is the height of h.
- The horizontal distance is of 3m.
Hence:
tan(45º) = h/3.
1 = h/3.
h = 3 m.
If the ladder slides 1 m down, the height will be of 2m, hence the angle will be given as follows:

Answer:
(a)12%
(b)20%
(c)49%
Step-by-step explanation:
(a)In the age group 58 and above:
- Number in favor of building the skateboard ramps=6
- Number opposed to building the skateboard ramps=44
- Total = 50
Percentage of those in favor = 
(b)In the age group 18-37
- Number in favor of building the skateboard ramps=40
- Number opposed to building the skateboard ramps=10
- Total = 50
Percentage of those opposed to it = 
(c)
- Total Number of those in favor of building the skateboard ramps=73
- Total Number opposed to building the skateboard ramps=77
- Total = 150
Percentage of those in favour =
