Question

A wire is attached 35 feet above the ground to a telephone pole. The wire makes anangle of 45° with the ground, as shown below.35 ft45°What is the length of the wire?

Answer 1

`\text{lenght of wire = }\frac{opposite\text{ side}}{\sin\text{ angle}}\text{ = }\frac{35}{\sin\text{ 45\degree}}\text{ =}\frac{35}{\frac{\sqrt[]{2}}{2}}\text{ = 35}\sqrt[]{2}`
`\sin \text{ 45\degree=}\frac{\sqrt[]{2}}{2}`

`\text{Answer = 35}\sqrt[]{2}\text{ ft}`
