Answer:

x=16°

Step-by-step explanation:

Soh-Kah-Toa

you will use Toa

that's tangent = $\frac{opposite}{adjacent}$

tan-1( $\frac{10}{36}$ )=15.524111

*it's negative because you're solving for an angle

*round to the nearest degree

so, x=16°

How to find the area of composite polygon that have a base of 16 meters height of 18 meters and a height of 11 meters.

LenaWriter [7]

The area of the composite polygon is:

$\boxed{A_{T}=376 \ m^2}$

<h2>Explanation:</h2><h2 />

Hello! remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any figure, so I'll choose the figure below in order to illustrate this problem. A composite polygon is a polygon that can be divided into two or more basic shapes. So here we have a composite polygon formed by a triangle and a rectangle. So:

$A_{total}=A_{T} \\ \\ A_{triangle}=A_{tr} \\ \\ A_{rectangulo}=A_{r} \\ \\ \\ A_{tr}=\frac{b\times h}{2} \\ \\ b:Base \ of \ the \ triangle \\ \\ h:height \ of \ the \ triangle \\ \\ \\ A_{r}=B\times H \\ \\ B:base \ of \ the \ rectangle \\ \\ H:height \ of \ the \ rectangle$

So the area of the composite figure is:

$A_{T}=\frac{16\times 11}{2} + 16\times 18 \\ \\ A_{T}=88+288 \\ \\ \boxed{A_{T}=376 \ m^2}$

87 + 89 divided by 2 x 2 x 2 x 6 x 5 x 4 x 2 x 12 x3

Fittoniya [83]

First you add 87 +89 which equals 176.
second you multiply all the numbers you want to divide, which, to save time, equals 69,120

176 / 69,120 = 0.0025462962963 (0.003 if needing to round)
