Set up multiplication/division of proportions to cancel out units that you don't want and to introduce units that you do want in your final solution...
2678cm(in/2.54cm)(ft/12in)=2678/30.48 ft≈87.86 ft (to nearest hundredth)
Your friends house<2,640 feet. 264 times 10 is 2,640 feet and your friend is closer.
Step-by-step explanation:
Here with reference angle 45°
Hypotenuse ( h) = y
Perpendicular (p) = x
base (b) = 5√2
We know
tan 45° = p/b
1 = x / 5√2
Therefore x = 5√2
Now
h = √(5√2)^2 + 5√2)^2
= √ 50 +50
= √100
= 10
