Geometry angles problem

Step-by-step explanation:

we know that

Two angles are supplementary when their sum is equal to 180 degrees

we have

-----> equation A

Two angles are complementary when their sum is equal to 90 degrees

we have

-----> equation B

equate equation A and equation B

solve for x

Find the measure of angle ABC

substitute the value of x in equation A or equation B

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.
