Answer:
Step-by-step explanation:
SOHCAHTOA
Cosine = Adjacent / Hypotenuse (Hypotenuse is the side opposite from the right angle)
The Hypotenuse is BT which has a measure of 25
Legs are the two sides that are not the Hypotenuse.
The adjacent leg to Angle B is SB which has a measure of 20.
Plug the measures in to get SinB = 20/25
Answer:
36
3
5
12
Step-by-step explanation:
The circumfrence of a circle is as follows
2πr
For this question π=3.14
So we have
113.04=2πr
solve for r
r= 18
which means that diameter is 36
Just do the same thing with the other questions
18.84=2πr
r=3
31.4=2πr
r=5
37.68=2πr
r=6 which means that the diamater is 12
I think it is A because I just took the test
There is no solutions when you solve this algebraically, it ends up with 4 = 0 which is not true. When you graph it, the two equations are parallel, so there is no real solution.
