Question

The side lengths of a 45-45-90 triangle are in the ratio 1:1:√2. What is sin 45°?

Answer 1

Answer:

$\frac{\sqrt{2} }{2}$

Step-by-step explanation:

To find the value of sin 45° we divide the opposite side length with hypotenuse

$\frac{1}{\sqrt{2} }$  we then multiply this by $\sqrt{2}$ because denominator cannot be irrational

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