<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
1) x + 146° = 180° (sum of angles in a straight line)
x = 34°
2) x + 62.9° = 90° (complementary angles)
x = 17.1°
3) x + 105° = 180° (sum of angles in a straight line)
x = 75°
The value of x in each figure is 34°, 17.1° and 75° respectively.

Answer:
30%
Step-by-step explanation:
In this question, we are to calculate the percentage of students who are female and do not play instruments.
We can first infer this from the table;
The number of females who do not play instruments = 64
The percentage of females who do not play instruments = number of females who do not play instruments/total number of students surveyed * 100%
That will be;
64/213 * 100% = 30.04 which is approximately 30%
