Answer:
The estimated cost of 21 calculators is approximately $4,800
Step-by-step explanation:
we know that
To estimate the total cost of the calculators, multiply the cost of one calculator by the number of calculators, but first round the numbers to the tens place
so
Cost of one calculator-----> $241
Round to the tens place ----> $241=$240
Number of calculators ----> 21
Round to the tens place ----> 21=20
The estimate cost is
(240)(20)=(240)(10)(2)=$4,800
therefore
The estimated cost of 21 calculators is approximately $4,800
third side =√{30²+16²)=34
sin theta/2=16/34
theta/2=sin-¹(16/34)
theta=28.07×2=56.14
