Answer:
sqrt(15)/2 = g
h = sqrt(5) /2
Explanation:
We know that sin 30 = opposite / hypotenuse
sin 30 = h/ sqrt(5)
Multiply by sqrt(5) on each side
sqrt(5) sin 30 = h
sqrt(5) (1/2) = h
h = sqrt(5) /2
cos 30 = adjacent/ hypotenuse
cos 30 = g / sqrt(5)
Multiply each side by sqrt(5)
sqrt(5) cos (30 ) = g
sqrt(5) (sqrt(3)/2) = g
sqrt(15)/2 = g
