Paladinen [302]
\text{Area of the triangle = 6 unit}^2Explanation:

The triangle is right angled.

The formula for area of the triangle:

\begin{gathered} A\text{ = }\frac{1}{2}bh \\  \\ b\text{ = base} \\ h\text{ = height} \end{gathered}

base = 3

height = 4

substitute the values:

\begin{gathered} \text{Area of the triangle = }\frac{1}{2}\times3\times4\text{ = 12/2} \\ \text{Area of the triangle = 6 unit}^2 \end{gathered}

Emir is standing in a treehouse and looking down at a swingset in the yard next door. The angle of depression from Emir's eyelin
boyakko [2]
<h3>Answer:  24 feet  (Choice D)</h3>

=============================================

Explanation:

Refer to the diagram below. The goal is to find x, which is the horizontal distance from the base of the tree to the swing set.

Focus on triangle BCD.

The angle B is roughly 30.26 degrees, and this is the angle of depression. This is the amount of degrees Emir must look down (when starting at the horizontal) to spot the swing set.

We know that he's 14 ft off the ground, which explains why AB = CD = 14.

The goal is to find BC = AD = x.

---------------------------

Again, keep your focus on triangle BCD.

We'll use the tangent ratio to say

tan(angle) = opposite/adjacent

tan(B) = CD/BC

tan(30.26) = 14/x

x*tan(30.26) = 14

x = 14/tan(30.26)

x = 23.9965714046732

That value is approximate. Make sure your calculator is in degree mode.

That value rounds to 24 feet when rounding to the nearest whole foot.

If ON = MN, find MN.
Furkat [3]
Use Pythagorean theorem.

[tex]|ON|^2+|MN|^2=|OM|^2\\\\x^2+x^2=8^2\\\\2x^2=64\ \ \ \ |divide\ both\ sides\ by\ 2\\\\x^2=32\to x=\sqrt{32}\\\\x=\sqrt{16\cdot2}\\\\x=\sqrt{16}\cdot\sqrt2\\\\\boxed{x=4\sqrt2}

Answer: |MN| = 4√2.

What is the slope of the line that passes through the pair of points (-2.5,6.1) and (-2.5,3.1)
podryga [215]
(-2.5,6.1)(-2.5,3.1).....notice how ur x values are the same. This means that u have a vertical line which has an undefined slope.

IF ur y values would have been the same, u would have had a horizontal line which has a 0 slope.
