Answer:
The unknown number is 12
Step-by-step explanation:
2(x+26)=76
or,x+26=76÷2
or,x=38-26
Therefore,x=12.
We can't tell. Contrary to what you led us to believe, there is no triangle illustrated, and we need one for the new one to be similar to.
#1 - 8/7 7:8
#2 -3:4
#3 - 3:8
#4 -4:3
<span>base area = 25 sq meters
area = PI*radius^2
radius = sq root [area / PI]
</span><span>radius = sq root (25/PI)
</span>base radius = <span>2.8209479177 meters

Cylinder Volume = </span><span>π <span>• r² • height
Therefore,
</span></span><span>Cylinder height = Volume / [pi*radius^2]
</span>Cylinder height = 225 / [PI*<span>2.8209479177 ^ 2]
</span>Cylinder height = 225 / [PI *

<span>Cylinder height = 225 / 25
</span><span>Cylinder height = 9 meters

When a jogger runs south and then turns west, we have right angle between segment 0.8 mi and segment to the west. So it is legs of the right triangle.
1.7 mi is hypotenuse.
hypotenuse² =(leg1)²+(leg2)²
1.7²=0.8² + (leg2)²
(leg2)²=1.7²-0.8² = 2.25 mi²
leg2=√(2.25 mi²)
leg2=1.5 mi
Answer is 1.5 mi.
