Answer:
A circle with circumference 18 had an arc with 120 central angle.
=> Radius of that circle: R = 18/(2 x pi) = 2.86
=> Length of that arc: L = R x 120 x pi/180 = 2.86 x (2/3) x pi = 5.99
Hope this helps!

Answer:
h(a + 2) = 4a + 3
Step-by-step explanation:
∵ h(x) = 4x - 5
∴ h(a + 2) = 4(a + 2) - 5
∴ h(a + 2) = 4a + 8 - 5 = 4a + 3
Hi there!
Tangent is a trigonometry ratio, and it is the value of the side opposite the angle over the side adjacent to the angle.
The side that is opposite angle B is side CA which is equal to 2.
The side that is adjacent to angle B is side CB which is equal to 1.
Therefore, the tangent ratio for angle B is 2/1.
(The adjacent side cannot be side BA because it is the hypotenuse.)
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer: 2
Step-by-step explanation: add 10 to both sides so -10+10=0 and -6+10=4
then you have 2x=4 simplify
Answer:$344
1/5 of 400 is 80 so if you subtract that it would be $320
1/50 of $400 is 8 so if you multiply that by 3,3/50 of $400 is(8*3)24 so $320+$24=$344
