the first one
Step-by-step explanation:
Hey There!
Look at the image for the rule of a 30- 60 - 90 triangle
x = 5
the hypotenuse would be x2 so 10
the longer leg would be x
So the first triangle is the right answer
A) Sqrt(4^(2/3x)) * 2^x = 1
4^(1/3x) * 2^x = 1
2^(2/3x) * 2^x = 1
2^(5/3x) = 1
Log(2)1 = 5/3x
0 = 5/3x
x = 0
2/5 of the students is equivalent to 394 students. The total number of students involved is thus 394*5/2.
