Find the missing side lengths. Answers are in simplest radical form with the denominator rationalized
Roman55 [17]

Answer:

Option B.

Step-by-step explanation:

The given triangle is a right angle triangle.

In a right angle triangle,

\tan \theta=\dfrac{Perpendicular}{Base}

In the given triangle,

\tan (45^{\circ})=\dfrac{v}{7}

1=\dfrac{v}{7}

7=v

Using Pythagoras theorem, we get

hypotenuse^2=Perpendicular^2+Base^2

u^2=v^2+7^2

u^2=7^2+7^2

u^2=2(7^2)

Taking square root on both sides, we get

u=\sqrt{2(7^2)}

u=7\sqrt{2}

Therefore, the correct option is B.
