Question

Find the length of the missing sides in the triangle

Answer 1

Answer:

b. $\displaystyle x ≈ 9,9, y = 7$

Step-by-step explanation:

In a 45°-45°-90° triangle, both legs are congruent $\displaystyle [x],$whereas the hypotenuse is represented by $\displaystyle x\sqrt{2}.$ So, evaluate:

$\displaystyle hypotenuse \hookleftarrow x\sqrt{2} \\ \\ 9,8994949366... = \boxed{7\sqrt{2}}$

Therefore, you have this:

$\displaystyle 9,9 ≈ x$
