Heya mate, Here is ur answer
1) d=3
a15 = a+14 d
a15 =a +14×3
a15 =a +42
a9=a+8d
a9=a + 8×3
a9= a +24
a15 -a9
= a +42-(a+24)
= a +42-a -24
= 18
==============================
2) Shadow/height = √3/1
shadow(base) /height (perpendicular)=√3
Cot 30° =√3
Tan 60°=√3
So, sun's elevation is 60° .
===============================
Warm regards
