Answer number 6 for me asap and i will thank u if its correct

D

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, thus

x + 5 + x + 7x - 5 = 180, that is

9x = 180 ( divide both sides by 9 )

x = 20 → D

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.
