Answer: angle y is 50°
Step-by-step explanation:
t + 2t - 30 = 90
3t -30 = 90
3t = 90+30
t = 120/3 = 40 = angle X
Angle y = 2t-30
y = 2*40-30
=80-30 = 50
Answer:
320 students
Step-by-step explanation:

Answer:
150ft
Step-by-step explanation:
it says it was dropped meaning it will go down in height till eventually hitting zero

h=-16(0)^2 + 150 h=150ft
h=-16(1)^2 +150 h=134ft
