Answer 2

Answer:

Since the triangle is right angled,Here we can use trigonometry

so here we need to find x

since x is opposite to 45°, we can take sin theta

sin 45° = opposite side / hypotenuse

sin 45° = x / 5

( sin 45° = 1/√2 )

so,

1/√2 = x/5

x = 5/√2

rationalising the denominator

x = 5/√2 * √2/√2

x = 5√2/2

therefore the answer is option c that is x = 5√2/2

hope it helps you
