Janelys leans a 16-foot ladder against a wall so that it forms an angle of 61^{\circ} ∘ with the ground. How high up the wall do

Lilit [14]

The height the ladder reaches up the wall is $13.99ft$

The ladder, the wall, and the ground form a right-angled triangle.

The ladder is the hypotenuse, or the longest side, of the triangle. The wall is opposite of the angle, $61^{\circ}$ , that the ladder makes with the ground.

The formula relating the angle the ladder makes with the ground, the ladder, and the wall is the trigonometric ratio

$sin 61^{\circ}=\dfrac{\text{wall height}}{\text{ladder length}}$

substituting the values for the ladder length, and $sin61^{\circ}$ , and solving, we get

$0.8746=\dfrac{\text{wall height}}{16}\\\\\text{wall height}=0.8746\times16\approx13.99ft\text{ (to the nearest hundredth)}$

Please help me find the distance between the points (5,4) and (1,-2) and express the answer in simplest radical form.

finlep [7]

The distance between two points can be calculated using the following formula:
distance = sqrt [ (x2-x1)^2 + (y2-y1)^2]

Now, we are given the two points (5,4) and (1,-2)
Substitute with the given points in the above equation to get the distance as follows:
distance = sqrt [(1-5)^2 + (-2-4)^2]
distance = sqrt [16+36] = sqrt[52]
distance = 2√13 = 7.2111 units
