The answer would be 19.87
7.2*12*.23= 19.872
Because two is lower then 5 we could round to 19.87
Answer:
you find the difference of 5 1/4 and 11 1/5 so what that means is
difference = subtract
so you do 11 1/5 - 5 1/4 = 5 19/20 = 5 19/20
Step-by-step explanation:
angle at a straight line is =180
4+5+x=180
let x be angle at the tower
9+x=180
x=180-9
x=171°
and x is divide in to two then is 2x
there for
2x=171°
x=171/2
x=85.5°
then sin85.5°= 90/y
let y be the unknown feet
0.9969=90/y
y0.9969=90
y=90/0.9969
y=90.3ft.
4x+10=-26
4x = - 36
x = - 9
Answer for x is -9
