Answer:
60 degrees.
Step-by-step explanation:
BC is parallel to the x axis (because B and C have the same y-coordinate).
Slope of AB is 3/√3 = √3
so the angle AB makes with the axis = angle it makes with BC
= arctan(√3)
= 60 degrees.

Answer:
15y-2
Step-by-step explanation:
Please use parentheses if needed, this has me confused but without them, I solved it.
(-2y)(3)+3y-3y+7y(3)+1+2+5
-6y+3y+-3y+21y+1+2+-5
Combine like terms
(-6y+3y+-3+21y) + (1+2+-5)
15y + -2
Answer again: 15y - 2.
∵h = -16t + 541
So, after 2 seconds ⇒⇒⇒ t =2
substituting in the equation of h
∴ h = -16*2 + 541 = 509 feet
