Question

Can someone help me please

Answer 1

39 degrees.

Explanation:

the line is 180 degrees. one of the angles is 51 degrees and another is 90 degrees because it shows us a square. 51 + 90 is 141. 180 - 141 is 39. so 39 degrees is your answer.

Answer 2

Explanation:

c + 51° + 90° = 180°

c + 141° = 180°

c = 180° - 141°

c = 39°
