Could you please solve this?

x = 12

Step-by-step explanation:

The ray from the vertex to the base is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

= ( cross- multiply )

3x = 36 ( divide both sides by 3 )

x = 12

x = 32.2

Step-by-step explanation:

cos theta = adj/hyp  where adj means adjacent side and hyp = hypotenuse

cos x =  11/13

Take the inverse cos of each side

arccos (cos c) = arccos (11/13)

x = 32.2042275

Rounding to the nearest tenth

x =32.2
