Answer:

  • 30 units

Step-by-step explanation:

<u>The ratio of sides in 45º-45º-90º triangle is:</u>

  • a : b : c = 1 : 1 : √2

<u>If both a and b are 15√2, the hypotenuse is:</u>

  • c = 15√2*√2 = 15*2 = 30

Let's consider the given triangle be ∆ABC. First of all we must know the unique property of triangle 45° - 45° - 90°. In this the ratio of sides of the triangle is given by,

\implies a : b : c = 1 : 1 : √2

Now as per your question elaborating it by placing values of sides in our ∆ABC,

Where,

  • c = hypotenuse
  • a & b = two sides

:\implies\sf{c = 15 \sqrt{2}  \times  \sqrt{2} }

:\implies\sf{c = 15 \times  \sqrt{2}  \times  \sqrt{2} }

:\implies\sf{c = 15 \times 2}

:\implies\sf{c = 30}

  • The length of hypotenuse is <u>3</u><u>0</u><u>c</u><u>m</u><u>.</u>

<em>Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.</em>

<em>                               b² = a² + c² - 2ac(cosB)</em>

<em>Substituting the known values,</em>

<em>                          (1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)</em>

<em>The value of B from the equation is 48.6°. </em>
