Answer:
46.63 ft
Step-by-step explanation:
I've drawn and attached a triangle diagram to represent this elevation and distance of balloons.
Now, from the diagram attached, we can see the angle at which June must look up to see Armando is 25°.
Also, the height of Armando above June is represented by "x".
Thus, using pythagoras theorem, we can find x.
Thus;
x/100 = tan 25
x = 100 × tan 25
x = 100 × 0.4663
x = 46.63 ft
Answer:
Step-by-step explanation:
From the information given,
Let the two digits that Chen writes down to be p and q
where,
q will be in the unit place and p will be in the tens place.
So, the value of the digit = 10p + q
So, if he swapped the number, he will have 10q + p
However,
the new number determined is thrice more than the 1/3 pf the original number.
i.e
the 1/3rd of the original number =
=
thrice more than that will be =
∴
multiply through by 3, we have :
10p+q + 9 = 30q + 3p
collecting the like terms, we have:
10p - 3p +q -30q +9 = 0
7p - 29q +9 = 0
7p - 29q = -9
Therefore, p,q lie between 0 and 9
Therefore, the possibility of the original number is p = 7 and q = 2
