Cos theta = 75/115
theta = cos^-1 (75/115)
theta = 49.2 degrees
Hope this helps! Because when you would fill in the variables 0=0 which which make the expression too that they’d equal the same.
Answer:
Step-by-step explanation:
h=16t^2+98=?
subtract 98 from both sides to get
h-98=16t^2
(the 98 on the right cancels)
now divide by 16 on both sides
h-98/16=t^2
(the 16 on the right cancels)
lastly take the square root on both sides
square root(h-98/16)= t
if you know what h is fill it in and it will give you your answer
Im not 100% sure!!
