Question

I need help on this on my bros​

Answer 1

Explanation:

By 30°-60°-90° triangle theorem:

`15 = (1)/(2) * c.. (side\:opposite \: to \:30°)\\ c = 15 * 2 \\ \\ \huge \red{ \boxed{c = 30 \: m}} \\ \\ b = ( √(3) )/(2) * c.. (side\:opposite \: to \:60°) \\ \\ b = ( √(3) )/(2) * 30 \\ \\ \huge \purple{ \boxed{b = 15 √(3) \: m}}`
