Answer:
5
Step-by-step explanation:
Since this is a right triangle we can use trig functions
sin theta = opp /hyp
sin 30 = x / 10
10 sin 30 = x
10 * 1/2 = x
5 =x

Answer:
Pythagoras theorem. 20^2 times 18^2 = distance^2
Answer:
∠B = 22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, hence
120 + x + x + 16 = 180
2x + 136 = 180 ( subtract 136 from both sides )
2x = 44 ( divide both sides by 2 )
x = 22 = ∠B
