If x = 3 + 2 ( the square root of2) , find square root x + 1/ sqaure root of x and
If x = 3 - 2 ( the square root of 2) , find the value of the whole square of x - 1/the whole square of x

the answer is c. 23/3

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
