Answer:
Step-by-step explanation:
We can add 9 to both sides of the equation to get 
.
We can divide both sides of the equation by 21 to get 
.
We take the square root of both sides of the equation to get 
.
However, that isn't in the form we need.
We know that 
so the answer is really and we're done!

Answer:
В (50°)
Step-by-step explanation:
m∠XWY=180-95=85°
x=180-(m∠XWY+m∠XYW)=180-(85+45)=50°
(d(5) -d(3))/(5 -3) = (350 -126)/2 = 112 . . . . . meters/second
112 m/s; it represents the average speed of the object between 3 seconds and 5 seconds
