Answer:
Explanation:
using the Pythagorean theorem a² + b² = c²
in this triangle a = x and b = x so x² + x² = c² c is the hypotenuse
x² + x² = c²
2x² = c² since c = 23 solve for x
x² = c² / 2
x = ± √(c² / 2)
x = ± √(23² /2)
= ± √(529 /2)
= ± √(264.5)
= 16.26 x can't be negative
That is correct but it doesn't answer the question
x = ??? / √xx
sin 45 = √2 / 2 which equals x / 23
√2 / 2 = x / 23
x = 23 (√2 / 2)
= 23 (√2) / 2 divide the √2 numerator and demenator
= 23 (√2)/√2 / (2 / √2)
= 23 / (2 / √2)
Sorry I have no idea what goes in the green box
