There's no solution set.
you've just given a function of x with nothing to do with it. there is nothing to solve.
Step-by-step explanation:
okay
I think you should use the method of tan 30
and then find x by using pythagorean theorem
71 inches X 36 inches = 2556 sq inches
convert sq.feet to sq.inches.
12 sq. feet = 1 sq. inch
2556 sq. feet × 1 sq. inch ÷ 12 sq. feet = 213 sq. inches (sq. feet ÷ sq. feet cancels out the feet variable leaving sq. inch)
(70+71+72+x)/4 ≥ 73
(213+x)/4 ≥ 73
213+x ≥ 73*4
213+x ≥ 292
-213 -213
x ≥79
Check:
(70+71+72+80)/4
292/4
73.25
Your Answer:
x ≥ 79
