Answer:

[tex]7\sqrt{2}[/tex] meters

Step-by-step 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 [tex]a[/tex] and the hypotenuse that you are trying to find (u) is represented by [tex]a\sqrt{2}[/tex]

Therefore, your answer is [tex]7\sqrt{2}[/tex] in simplest radical form.

Answer:

u= 7[tex]\sqrt{2}[/tex]

Step-by-step explanation:

The missing side is u

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

sin 45° = [tex]\frac{\sqrt{2} }{2}[/tex]

so :

  • u = 7*[tex]\frac{2}{\sqrt{2} }[/tex]
  • u = 14/√2
  • u = [tex]\frac{7*\sqrt{2} ^{2} }{\sqrt{2} }[/tex]
  • u = 7[tex]\sqrt{2}[/tex]
