<u>Given</u>:
The given triangle has three equal sides. Thus, the given triangle is an equilateral triangle.
The measure of one angle is (4x - 20)°
Since, it is an equilateral triangle, then all the three sides will be equal.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the triangle sum property.
Thus, we have;
Simplifying, we have;
Adding the like terms, we have;
Thus, the value of x is 20
If S is students and n is nonstudents
S = 3n + 11
541 = 6(3n + 11) + 7n
541 = 18n + 66 + 7n
475 = 25n
n = 19
19 nonstudents so then you put that number in the first equation
S = 3(19) + 11
S = 68
68 students attended the movie
