The Touring Bridge crosses the Arkansas River at a 36-degree angle to the river on one side. The river banks are parallel to each other. What is the angle the bridge makes with the river on the other side?

Answer 1

what is the meaning...............

Answer 2

In right triangle ABC, we have  Hence, the width of the river is metres.Height of brigde, DP = 3m

Now,

AB = AD + DB

In right triangle ABD, Angle A = 30°

So,

tan30° = PD/AD

\frac{1}{ \sqrt{3} } = \frac{3}{AD}

In triangle PBD, Angle B = 45°

So BD = PD = 3m

AB = DB + AD

Now, the

3 + 3 \sqrt{3}

3( \sqrt{3 + 1} )m

hope this helps u
