(6,3)
i think this is correct
I can do it using trigonometry.
Draw a line from O to the point where the circle touches the base line. This will be at right angles to EF and will have length 40. Then draw a line from A parallel to the base to meet OG at H.
consider triangle OAH:-
side OH = 40-25 = 15 cm
cos < AOH = 15/40 giving m < AOH = 67.976 degrees
So m < AOB = 67.976 * 2 = 135.95 degrees
in radians this is 2.37 radians (answer)
Part B:-
Answer:
(x+2) (x+4)
Step-by-step explanation:
x^2+6x+8
What 2 numbers multiply together to give us 8 and add together to give us 6
(2*4) =8
(2+4) = 6
(x+2) (x+4)
Answer:
B: -4
D: 8/3
