We can split the given figure in 2 right triangles:

So, in order to get the area of each triangle, we need to find the base, denoted by x in both of them. Since both are right triangles, we can to apply Pythagoresn theorem. By applying this theorem to right hand side triangle, we have

x^2+8^2=17^2

so we have

\begin{gathered} x^2+64=289 \\ then \\ x^2=289-64 \\ x^2=225 \end{gathered}

Then, x is given by

x=\sqrt{225}=15

Then, the area of the left triangle is given by

A_1=\frac{base\times height}{2}=\frac{15\times36}{2}=270in^2

Similarly, the area of the second triangle is given by

A_2=\frac{base\times height}{2}=\frac{15\times8}{2}=60in^2

Then, the area of the entire figure is the sum of the area of the 2 triangles, that is,

A=A_1+A_2=270+60=330in^2

Therefore, the answer is: 330 square inches

Answer:

Height of Tower = 41.8901 ft

Base to Ground Wire = 94.0905 ft

Step-by-step explanation:

So you want to find the opposing side of the angle, as well as the distance from the base to where the wire is attached to the ground. You would need to use CAH to find the ground, and SOH to find the height. To find the height or opposite, take the Sine of 24°, 0.4067, and times it by your hypoteneuse 103 to get an exact height of 41.8901 ft. Next, use the Cosine of 24°, 0.9135, and times that by your hypoteneuse 103 to get 94.0905 ft.

Here are the equations:

sin(24)=\frac{h}{103}

cos(24)=\frac{h}{103}

Levart [38]

Answer:

let the number be x

x-10=11*x

x-10=11x

-10=11x-x

-10=10x

x= -10/10

x= -1
