Answer:
7
Step-by-step explanation:
the side length of the largest square is x
2x-1=3x-8
-x=-7
x=7
Answer: 138°
Step-by-step explanation: since the line is crossing parallel lines the number opposite of your x is the same as 138°
Answer:
35 m/s
Step-by-step explanation:
Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m



This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s
v = 20 / 0.571 = 35 m/s
A = b+5
ab = 3300
(b+5)b = 3300
b² +5b -3300 = 0 (quadratic formula)
b=55
a=60 (by first relation)
