Answer:
2/7
Step-by-step explanation:
You would add what is in the parenthesees and you get 6/14 and if you simplify you get 3/7. So you would do 5/7 -3/7
Since the figure is a rhombus, the diagonals cut each other at right-angles and bisect each other, namely cut their vertices in equal halves.
what the dickens does all that mean? well, the angles at vertex C and vertex A are all twins, and therefore, ∡BCA = x, therefore

Answer:
x = 73/4
Step-by-step explanation:
Solve for x:
12 x - 39 = 180
Add 39 to both sides:
12 x + (39 - 39) = 39 + 180
39 - 39 = 0:
12 x = 180 + 39
180 + 39 = 219:
12 x = 219
Divide both sides of 12 x = 219 by 12:
(12 x)/12 = 219/12
12/12 = 1:
x = 219/12
The gcd of 219 and 12 is 3, so 219/12 = (3×73)/(3×4) = 3/3×73/4 = 73/4:
Answer: x = 73/4
If the number only has 2 digits, it could only be 91, because since the tens digit is 8 more than the ones digit, the tens digit is greater than or equal to 8. it cannot be 10 or more, because that would make the number over 100, leaving only 8 and 9. If the tens digit is 8, the ones digit is zero, and since it cannot be zero, then the tens digit must be 9, leaving the ones digit to be 1. So, the final answer is 91.
