Answer 1

u= 7
`√(2)`

Explanation:

The missing side is u

• sin 45°=7/u switch u and sin 45°
• u = 7/sin°45

sin 45° =
`(√(2) )/(2)`

so :

• u = 7*
  `(2)/(√(2) )`
• u = 14/√2
• u =
  `(7*√(2) ^(2) )/(√(2) )`
• u = 7
  `√(2)`

Answer 2

`7√(2)` meters

Explanation:

This is a 45 45 90 triangle. This means that two sides of the triangle are equivalent. In this type of triangle, the two equal sides are represented by
`a` and the hypotenuse that you are trying to find (u) is represented by
`a√(2)`

Therefore, your answer is
`7√(2)` in simplest radical form.
