Question

Plz help me find a on the triangle show work plz​

Answer 1

x = sqrt(11)

Explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse

x^2 +(sqrt(5))^2 = 4^2

x^2 +5 = 16

x^2 =16-5

x^2 = 11

Taking the square root of each side

x = sqrt(11)
