Answer:
Find the Central Angle from the Arc Length and Radius
You can also use the radius of the circle and the arc length to find the central angle. Call the measure of the central angle θ. Then: θ = s ÷ r, where s is the arc length and r is the radius.
Step-by-step explanation:
x2+10=0A.B.C.D.
it is A because 0 can't enter into a letter if it can enter then it will be the same letter
B. x² - 13x + 42
(i) U' = Φ
(ii) A∩A' = Φ
(iii) A – ( B U C) = {5,7,9}
(iv) A' U ( B U C ) = {2,4,6,8,10}
(v) A' U ( B' ∩ C') = {2,4,5,6,7,8,9,10}
The correct option is B) To help people prepare for the future.
The other three options are irrelevant to scientific research on environment .
Hence the correct option is B)
3 1/8 means 8 x 3 + 1 = 25/8
4/5 x 25/8
= 4x25/5x 8
= 100/40
= 5/2
