Add 3 on both sides
8y - 3 + 3 = 13 + 3
8y = 13 + 3
8y = 16
Divide 8 on both sides
8y/8 = 16/8
y = 16/8
y = 2
y = 2
75 * 5 = 375
Hope I helped! :)
Turn 39% into a decimal
0.39
"of" means to multiply
so we get
0.39 * 72 = x
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:
