Answer:
x = 5 , y = 5![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° =
, cos30° =
, then
sin30°=
=
=
( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° =
=
=
( cross- multiply )
2y = 10
( divide both sides by 2 )
y = 5![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
In numbers and a variable it is 8x-6

Answer:
Number of students = 441 Students
Step-by-step explanation:
Given:
Percent of women = 40%
Percent of women = 35.5%
Total number of people = 1,800
Find:
Number of students
Computation:
Percent of student = 100% - 35.5% - 40%
Percent of student = 24.5%
Number of students = 1,800 x Percent of student
Number of students = 1,800 x 24.5%
Number of students = 441 Students
