Question

If the measures of the triangle are 45°,45°,90° then the length of each side containing the right angle is​

Answer 1

Answer: option b

Step-by-step explanation:

Let one side containing the right angle is​ x

Then the other side containing the right angle is also​ x because it is an isosceles triangle ( two angles are 45 and 45)

Then hypotenuse =

$\sqrt{x^{2}+ x^{2} } \\\\= \sqrt{2x^{2} } \\\\= \sqrt{2}x$

since hypotenuse = $\sqrt{2} x$

$\frac{1}{\sqrt{2} } * \sqrt{2} x = x$

i.e  $\frac{1}{\sqrt{2}} }$ x hypotenuse = length of each side containing the right angle
