Mathematics
1 answer:
BlackZzzverrR [31]3 years ago
8 0

Answer:

27

Step-by-step explanation:

CDE is a right angle so the sum of CDF and FDE is equal to 90

2x + x + 9 = 90 add like terms

3x + 9 = 90 subtract 9 from both sides

3x = 81 divide both sides by 3

x = 27

Find the slope of the line y=2
alexira [117]

Explanation: y=2 is a horizontal line, which has a slope of zero. x is the only variable that is changing, as y is always equal to 2 . Since we have no change in y , we have no "rise", therefore the slope is zero.
