The measure of the indicated angle to the nearest degree is 47°.

<h3>What is the measure of the angle?</h3>

Mrs lane took a survey of the types of pants her students were wearing. She collected the data of the types of pants her student
kirill [66]
It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.
Total number of students wearing jeans = 10
Total number of students wearing shorts = 9
Total number of students wearing capris = 2
Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)
                                                                                            = 21
Now percentage of students wearing shorts = (9/21) * 100
                                                                       = (3/7) * 100
                                                                       = 300/7
                                                                       = 42.85 percent
So a total percentage of 42.85% of the students were wearing shorts.
