Answer:
Step-by-step explanation:
In An A.P. ,
a = sin^2 5 °
d = 5°
l = a+(n-1)d.
sin^2 180° = sin^2 5° +(n-1) 5°
sin^2 180° = sin^2 5° + 5n° - 5°
By Dividing Both Sides By 5°,
sin^2 36° = sin^2 + n - 1
sin^2 36° - sin^2 = n - 1.
36 ° = n - 1.
n = 37.
Sum = n/2 (a + l)
37/2(sin ^2 5°+ sin^2 180°)
18.5(0.0075 + 0)
18.5 * 0.0075
0.13875
