First option is correct
because transversal rules make it that the angle that’s next to the 9x-60 angle equal to 51 and their total is 180 degrees
( 1635 ÷ 24 ) • 100 = monthly income
1635 ÷ 24 = 68.125
68.125 • 100 = $6812.50 a month
You have to add all the scores and dived by the 20 students, the result is 65.85%
3x^2 -2root(6)x + 2 = 0
(root(3)x)^2 -2[root(3)x]root(2)+ (root(2))^2 = 0
let a = root(3)x and b = root(2)
a^2 -2ab + b^2 = 0
(a - b)^2 = 0
by the null factor rule,
a - b = 0
sub back in a and b
root(3)x = root(2)
x = root(3)/root(3)
