Question

Determine the value of x. images attached.

Answer 1

The answer is option A

Explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of x

We use cosine to find the value of x

That's

`\cos(45) = (1)/(x) \\ x \cos(45) = 1 \\ x = (1)/( \cos(45) ) \\ \\ \\ \boxed{ x = √(2) }`
