L = liz's age now
J = Jack's age now
L-1 and J-1 are their ages one year ago
L-1=3(J-1)
L-1=3J-3
L=3J-3+1
L=3J-2 (to be used later)
L+2 and J+2 are their ages in two years
L+2=2(J+2)
replace L by 3J-2
3J-2+2=2(J+2)
3J=2J+4
3J-2J=4
J=4 is Jack's age now
L-1=3(J-1)
L-1=3(4-1)
L-1=3*3
L-1=9
L=9+1
L=10 is Liz's age now
Answer:
![18.98\°](https://tex.z-dn.net/?f=18.98%5C%C2%B0)
Step-by-step explanation:
Let
x-----> the angle of depression
we know that
The sine of angle x is equal to divide the altitude (opposite side to angle x) by the distance from the runway (hypotenuse)
![sin(x)=\frac{2.7}{8.3}](https://tex.z-dn.net/?f=sin%28x%29%3D%5Cfrac%7B2.7%7D%7B8.3%7D)
![x=arcsin(\frac{2.7}{8.3})=18.98\°](https://tex.z-dn.net/?f=x%3Darcsin%28%5Cfrac%7B2.7%7D%7B8.3%7D%29%3D18.98%5C%C2%B0)
