Answer: 24/7 as a mixed number is 3 3/7
Step-by-step explanation:
X - ⅙X = - ½ - ⅓ ==> ⅚X = - ⅚ ==> X = -1
Rule: For any quadrilateral, the four angles always add to 360 degrees
A+B+C+D = 360
A+95+100+90 = 360 ... plug in the given angles
A+285 = 360
A+285-285 = 360-285 ... subtract 285 from both sides
A = 75
Answer: choice C) 75 degrees
