Answer:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x = 
Then
∠ BOC = 2x = 2 ×
=
≈ 54.67° ( to 2 dec. places )
Answer:
laptop/phone
As the computer advanced, transistors were invented. They were smaller and allowed the computers to become smaller than ever. Slowly, the size of the computers decreased as more and more pieces were invented.
Step-by-step explanation:
The answer is D because, as decimals, 4 1/3 would be 4.33(a repeating decimal) and 4 3/5 would be 4.6, and 4.4 is between those two numbers. I hope this helps.
Answer: a= x^2 + 4x
Step-by-step explanation:
length= x
width= x+4
area= length x width
area = x(x+4)
area= x^2 + 4x
hope this helps :)
I believe it would be fifteen.
