5 1/2 = 5.5, 60 3/8 = 60.375
6a+5.5a=60.375
11.5a=60.375
a= 60.375/11.5 = 5.25 or 5 1/4 feet
Answer: a/7 + 1/7

Answer:
Step-by-step explanation:
Consecutive interior angles are supplementary.
(x -20)° +(4x +15)° = 180°
5x = 185 . . . . . . . . . . . . . . divide by °, add 5
x = 37 . . . . . . . . . . . . divide by 5
__
74° +(5y -4)° = 180°
5y = 110 . . . . . . . . . . . divide by °, subtract 70
y = 22 . . . . . . . . . . divide by 5
solution:
Since, it’s a standard cone opening up on the positive x – axis therefore,
X = √y²+z²
And because it has a vertex at (7,0,0)
Therefore the equation of surface is
X = 7 + √y²+z²
