Answer:
? = 14
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan ? = 8/33
Taking the inverse tan of each side
tan ^-1 ( tan ?) = tan ^-1 ( 8/33)
? =13.62699
To the nearest degree
? = 14
I believe the average rate of change is 1
If it costs 650 per kg then 500g will cost half of that as 500g is half of a kg so the answer is 650/2 = 325
First one is 4^2 or just 16.
Second one is using√ So what you want to do is 2√16
Hope this helps
