Explanation:


\underline{ \underline{ \text{Given}}} :

  • Hypotenuse ( h ) = 8√2
  • Perpendicular ( p ) = u
  • Base ( b ) = v

  • \tt{ \theta = 45 \degree}


\underline{ \underline {\text{To \: find}}} :

  • Value of u & v


\underline{ \underline{ \text{Solution}}}\: :


\tt{sin \: \theta = (p)/(h)}


\tt{ \sin(45 \degree) = (u)/(8 √(2) ) }


\tt{ (1)/( √(2) ) = (u)/(8 √(2)) }


\tt{ √(2 \: ) u = 8 √(2)}


\tt{u = (8 √(2) )/( √(2)) }


\tt{u = 8}

Again ,


\tt{tan \: \theta = (p)/(b)}


\tt{ \tan(45 \degree) = (8)/(v)}


\tt{1 = (8)/(v)}


\tt{v = 8}


\red{ \underline{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \tt{u = 8 \: and \: v = 8}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Answer:

Solution,

tan45 =
(u)/(v)

or, 1 =
(u)/(v)

or, v = u

Now,

Using Pythagoras Theorem,


(8√(2))^(2) = u^(2) +v^(2)\\or, 128 = u^(2) +u^(2)\\or, 128 = 2u^(2)\\or, u^(2) = 64\\\\or, u = 8cm = v
