In triangle ABC, angle B is 90° and angle A is 45° => triangle ABC is Isosceles triangle. That means side AB = BC

Also, side AC² = AB² + BC² = 2BC²
(6√2)² = 2BC² => 36*2
BC = 6

In triangle BCD, angle D is 90° and angle B is 60° => triangle BCD is semi Equilateral triangle. That means side BD = ½BC = 6/2 = 3 which is the value of X.

Good luck

ANSWER

C. 2.402

EXPLANATION

Given that:

log_{3}(2)  = 0.631

log_{3}(7)  = 1.771

We want to evaluate:

log_{3}(14) =   log_{3}(2 \times 7)

Use the product rule of logarithms.

log_{a}(mn)  = log_{a}(m) + log_{a}(n)

log_{3}(14) = log_{3}(2) + log_{3}(7)

log_{3}(14) = 0.631 + 1.771

log_{3}(14) = 2.402

The third choice is correct.
