Answer:

<h2>18 : 5</h2>

Step-by-step explanation:

\text{Convert}\ 1\dfrac{1}{2}\ h\ \text{to minutes.}\\\\\text{We know:}\ 1\ h=60\ min.\ \text{Therefore}\ 1\dfrac{1}{2}\ h=\left(1\dfrac{1}{2}\right)(60\ min)=90\ min\\\\\left(1\dfrac{1}{2}\ h\right):\left(25\ min\right)=(90\ min):(25\ min)=\dfrac{90}{25}=\dfrac{90:5}{25:5}=\dfrac{18}{5}=18:5

use the diagram to find the distance across the suspension bridge. Round your answer to the nearest foot
3241004551 [841]

Applying the tangent ratio, the distance across the suspension bridge is: 499.2 ft.

<h3>What is the Tangent Ratio?</h3>

Where we are given a right triangle, the tangent ratio is determined using the formula, tan ∅ = opposite side/adjacent side.

The diagram atatched beow whos the distance across the suspension bridge which consists of 6 identical right triangles.

Find the adjacent side of each right triangle using the tangent ratio:

∅ = 32

Opposite side = 52 ft

Adjacent side = x

Plug in the values into the tangent ratio:

tan 32 = 52/x

x = 52/tan 32

x = 83.2 ft.

Distance across the suspension bridge = 6(83.2) = 499.2 ft.

Therefore, applying the tangent ratio, the distance across the suspension bridge is: 499.2 ft.
