Find the value of X round to the nearest tenth. I need help.

x ≈ 22.1°

Step-by-step explanation:

Using the law of cosines, then

cosC =

with a = 19, b = 14, c = 8 and C = x, thus

cos x =

         =

         = , thus

x = ( ) ≈ 22.1° ( to the nearest tenth )

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
