To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
Answer:
10). m∠x = 47°
11). x = 30.96
Step-by-step explanation:
10). By applying Sine rule in the given triangle DEF,


Sin(x) = 
Sin(x) = 0.7309
m∠x = 
m∠x = 46.96°
m∠x ≈ 47°
11). By applying Sine rule in ΔRST,


x = 
x = 30.96
