Question

Bridge across a river makes an angle of 45° with the river bank.If the length of the bridge across the river is 150m, what is the width of river? *​

Answer 1

$\bold{ \underbrace{ ❥{ \purple{Solution}}}}$

In right triangle ABC, we have

$45° = \frac{BC}{AC}$

$⇒ \frac{1}{ \sqrt{2} } = \frac{BC}{150} </p><p></p><p>$

$⇒BC = \frac{150}{ \sqrt{2} } </p><p></p><p>$

$⇒BC = 75 \sqrt{2}$

Hence, the width of the river is 75√2 meters.
