Answer:
tan(60°)=x/7
7tan(60°)=x
First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.

12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.
Two digits are 10, 11, and 12.
Even numbers are 2, 4, 6, 8, 10, and 12.
So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)
P(Two digits or even) = 7/12

1/3 is the only fraction here that is greater than 3/10.
Convert these to decimals first, which can make it easier.
1/3 as a decimal is 0.33333333333333333333333333... which is greater than 0.3, which is 3/10.
3/11 as a decimal is 0.27272727272727.... which is LESS than 0.3, which is 3/10.
4/15 as a decimal is 0.26666666666666666666666666666666, which is less than 0.3, which is 3/10.
29/100 as a decimal is 0.29, which is less than 0.3, which is 3/10.
So the answer is 1/3.
