Answer:
x = 44.3°
Step-by-step explanation:
Redrawing the triangle,
To obtain x, we can apply the trigonometric relation :
Sin x = opposite / hypotenus
Opposite side = 6.5
Hypotenus = 9.3
Sin x = 6.5/9.3
x = sin^-1(6.5 / 9.3)
x = 44.34
x = 44.3°
-2/9 x 4/9 is -8
so the answer is -2/9
14-8=6. So far we have 3 km, then 6 divided by 2 which is 3 additional kilometers. 3+3 is 6 so the final answer is 6km
Altogether balls 4+2+3+5=14
P(red)=4/14=2/7
P(green)=2/14
P(yellow)=3/14
P(blue)=5/14
because it goes with replacement these probabilities are constant
