Math:
Well, you know that 12 inches goes into 1 foot.
So, let's start with just making everything into inches.
4 feet * 12 = 48+2 = 50 inches.
3*12 = 36 inches + 7 = 43 inches.
50 - 43 = 7.
Your answer:
7 inches.
9514 1404 393
Explanation:
Your different answers came about as a result of an error you made in the Pythagorean theorem calculation.
√(100 +100) = √200 = 14.142 . . . . same as vector calculation
Answer:
1). a = 9.42 m
2). b = 6.37 m
3). c = 4.48 m
Step-by-step explanation:
In the figure attached,
By applying tangent rule in triangle ADE,
tan47 = 
c = 
c = 
c = 4.476
c ≈ 4.48 m
Now we apply the same rule in triangle ACE,
tan37° = 
b = 
b = 
b = 6.37 m
Now apply the tangent in triangle ABE,
tan27° = 
a = 
a = 
a = 9.42 m
Sorry man I don't know if im write but try 28.78
