Question

Find the missing side to the triangle in the attached image.

Answer 1

x = 2√2

Pythagorean Theorem states that in a right triangle, a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse. Thus, 4 + 4 = x^2. Thus, x = the square root of 8, or 2√2

Answer 2

a^+b^=x^
2mulyiplyby2+ 2multiplyby2=x^
4+4=x^
Square root of 8 =square root of x^
X=2.83
