Hope it helps ya
what's its speed? well, it traveled √(52) in 2 seconds, so is simply √(52)/2, which is about 3.6 units per second.
2n = 3n - 5 (get all of n on one side by subtracting)
-1n = -5 (when you get here you have to divide by -1 to make n positive)
n = 5
Step-by-step explanation:
By angle sum property
7x-41+5x-12+2x+9 = 180
14x -44 =180
14x =224
x= 224/14
x= 16°
