Answer 1

Answer:

u= 7$\sqrt{2}$

Step-by-step explanation:

The missing side is u

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

sin 45° = $\frac{\sqrt{2} }{2}$

so :

• u = 7*$\frac{2}{\sqrt{2} }$
• u = 14/√2
• u = $\frac{7*\sqrt{2} ^{2} }{\sqrt{2} }$
• u = 7$\sqrt{2}$

Answer 2

Answer:

$7\sqrt{2}$ 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 $a$ and the hypotenuse that you are trying to find (u) is represented by $a\sqrt{2}$

Therefore, your answer is $7\sqrt{2}$ in simplest radical form.
