Check the picture below.
bear in mind that, a perpendicular line stemming from the right-angle like so, creates three similar triangles, a
large one, containing the other two smaller ones, a
medium and a
small.
so.. .we can just use the medium and small proportions.
solve for "x".
Supplementary, because both of the measurements are on a straight line which is equal to 80 degrees and x is equal too 31

Answer -1/12
Step-by-step explanation:
-7/12 + 1/2 cannot be added until you change 1/2 into 6/12.
To change 1/2 to 6/12, you have to multiply 1/2 by 6 because you want the same denominator. Since you can't just make a whole new fraction by changing the denominator, you have to multiply the numerator by 6 as well.
After changing the fraction, you should get -7/12 + 6/12.
now you can just add the numerators and denominators together and get -1/12!
