Answer:
<A = 30
<B = 150
Step-by-step explanation:
- cos<A = AK / AB
- AK = 4
- AB = 8
- Cos<A = 4/8
- Cos<A = 1/2
- A = Cos-1(0.5)
- A = 30 degrees
- Since BC and and AD are parallel, the interior angles of <A and <B sre supplementary.
- <A + <B = 180
- 30 + <B = 180
- <B = 180 - 30
- <B = 150
The answer would be Undefined
The toy rocket hits the ground when h(t) = 0.
So, h(t) = 0 = -9t^2 + 81.
Solving the equation,
-9t^2 = -81
Dividing by -9
t^2 = 9
Taking the square root.
t = 3
The answer is 3 seconds.
When u have an outlier, u want to use the median.....in this case, the median is 4
