Answer:
3 feet
Step-by-step explanation:
A 12-foot ladder is leaning across a fence and is touching a higher wall located 3 feet behind the fence. The ladder makes an angle of 60 degrees with the ground.
ladder is 12 foot
The ladder makes an angle of 60 degrees with the ground.
It form a right angle triangle . ladder is the hypotenuse
multiply 12 on both sides
x= 6
the distance from the base of the ladder to the bottom of the fence
x-3 = 6-3=3 feet
5 + 5 + 5 + 5 equals 550 lgjf8654
<span>Row 1 3 ft 91.44 cm
The ratio is 91.44 cm/ 3 ft = 30.48 cm/ft
</span><span>Row 2 6 ft 172.88 cm
The ratio is 172.88 cm / 6 ft = 28.81 cm/ft which ius not the same as 30.48 cm/ft.
</span><span>Row 3 7 ft 213.36 cm
</span>
<span>The ratio is 213.36 cm/ 7 ft = 30.48 cm/ft, which is the same as the first ratio.
Since 2 rows have the ratio 30.48 cm/ft, this ratio is correct. The ratio 172.88 cm / 6 ft is incorrect.
6 ft * 30.48 cm/ft = 182.88 cm
Answer: </span>
<span>B.Row 2 should show 6 feet is equivalent to 182.88 centimeters.</span>
3x + 6 = 27
step 1. subtract 6 from both sides
3x = 21
step 2. divide both sides by three to get x alone
x = 7
hope this helps
