The picture in the attached figure
we know that
if m ∠DAB=23.5°
then
arc DB=23.5°------> by central angle
the answer isarc DB=23.5°
ok
Probability to be yellow = 1/6
Probability to be orange = 1/6
Total probability = 1/6 x 1/6 = 1/36
Result = 1/36
So
1/2x+2=2/3x
convert to common fraction
1/2=3/6
2/3=4/6
3/6x+2=4/6x
subtract 3/6x from both sides
2=1/6x
multiply boh tisdes by 6
12=x
the tank can hold 12 gallon
The highest common factor of 60 and 150 is 30
And the lowest is 10
