Answer
72°
Step-by-step explanation:
sum of angles of a triangle= 180°
Let, the value of the unknown angle in the triangle be y°
Therefore,
30° + 42° + y° = 180°
or,
72° + y° = 180°
or,
y° = 180° - 72°
or,
y° = 108°
We know that a straight line = 180°
here, AM is a straight line (A till the arrow sign of the line is a straight line, you should have named the last point of the line drawn)
Therefore,
y° + x° = a straight line = 180°
we have known before that, y° = 108°
108° + x° = 180°
x° = 180° - 108°
x° = 72°
Answer:
<h2>The angle ABC is 70°.</h2>
Step-by-step explanation:
You can observe a representation of the problem in the image attached.
According to the inscribed angle theorem, the angle created by two chords is half of its subtended arc, that means

Now, observe that the arc AC has as central angle the angle ABC, according to the theorem, the subtended arc and its central are congruent.

Therefore, the angle ABC is 70°.
Any number multiplied by one is equal to itself. Therefore, six multiplied by one will be equal to six. As a result, one is the answer.
I would think it would be -39 points
