Find x. A. 22 B. 113–√ C. 222–√ D. 113√3

x = 31.12

Step-by-step explanation:

First find the base (hypotenuse) of the smaller triangle (the isosceles triangle):  Its three sides are 11, 11 and b.  b can be found using the Pythagorean Theorem:  b^2 = 11^2 + 11^2 = 242.  Then b = √242, or b = approximately 15.56.

b (which is approximately 15.56) is the shorter leg of the large (right) triangle.  The trig function needed to solve for x is the cosine:

                               adjacent side

cos 60 degrees =

                                  hypotenuse,

                                       15.56

which becomes (1/2) =

                                            x

Solving this for x, we get:  x = 2(15.56) = 31.12

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

well the answer to that is xoxoxo
