Answer: ≈ 8%
Step-by-step explanation:
Total number of students = total number of boys + total number of girls
Total number of students = 88 + 75
Total number of students = 163
10.2% of the boys have blue eyes , this means that 10.2% of 88 have blue eyes
x 88 = 8.976
Since we are dealing with humans , therefore , this means that 9 boys have blue eyes.
Also , 5.3% of the girls have blue eyes means that 5.3% of 75 have blue eyes. That is
x 75 = 3.975 , therefore : 4 girls have blue eyes.
In total , 13 students have blue eyes
Therefore , to calculate the % of students that have blue eyes , we have :
13/163 x 100 = 7.975460123
Therefore : ≈ 8% of the students have blue eyes
You use Sin-Cos-Tan. Since Tan is opposite and adjacent (SOH-CAH-TOA) we use that equations which is listed below. We rearranged the equation to get O alone and then plug everything in.
