Question

Find the value of x - A B C D

Answer 1

answer is C. 10

triangle is a right triangle

so you can use the Pythagorian theorem

and

2 out of the 3 sides are equal

so 2 sides are 5√2

5√2 = √5*5*2 = √50

Pythagorian theorem is

a^2 + b^2 = c^2

so

√50^2 + √50^2 = c^2

50 + 50 = c^2

100 = c^2

√100 = c

c = 10
