Answer:
The answer would be 2.
Step-by-step explanation:
U just subtract 39.21 -36.4= 2.81

There is only one repeating number, so we multiply both sides by

or

.

Now subtract the original number we had to both sides, which is the same as

or

So we have:

Divide 9 to both sides:

Multiply the fraction by 10 to get rid of the decimal in the numerator.

Simplify the fraction by dividing the numerator and denominator by 2:
Hello,
Please, see the attached file.
Thanks.
The does this differ from the original points is -32.5
The answer is 51°.
The top two lines are parallel to each other. Therefore alternate interior angles theorem applies. The bottom right corner that is underneath the line (for lack of a better description) is also 58°.
We also know that a triangle equals 180°. So 58+71= 129°.
So to find that missing angle we subtract 129 from 180 to get the 51°.
