three legs each 1.05m=105cm long
the height of the top of the tripod above the ground is 90cm
from right triangle formed by one leg (hypothenuse of triangle) and height (opp leg of triangle), we can find angle of inclination (leg to the horizontal) using sine function
sin%28alpha%29=opp%2Fhyp
sin%28alpha%29=90%2F105
alpha=sin%5E-1%2890%2F105%29
alpha=59°
