6/9 and 16/18 is what we will mainly look at since the whole numbers are the same. the common denominator is 18. so you would multiply 6/9 by 2 (both the numerator and denominator multiplied by 2 ) therefore you will get 12/18. Which is bigger 12/18 or 16/18? 16/18 is bigger, therefore you would say sixteen and 6/9 is less than sixteen and 16/18. your answer should be this below. :)
16,6/9 < 16, 16/18.
A=180-105
A=75
In the triangle
75+ 9x +12x =180
X=5

Answer:
Step-by-step explanation:
Given
height of two Poles are 60 and 80 ft
Distance between them is 100 ft
Let x be the distance of Pole of ht 80 ft from Point of stretch
thus length of rope is given by




differentiate w.r.t x we get

Put
to get minimum value

squaring

Rearranging


thus
