This is the concept of geometry, we are required to calculate for the length of the shortest side. The shortest side is the side opposite to the smallest angle; Therefore using sine rule we shall have:
a/sin A=b/sinB=c/sinC
let a=20 and A=100
b=x and B=20
thus the shortest side will be given by:
20/sin 100=x/sin 20
x=(20sin 20)/100
x=6.95 feet
The answer is 6.95 feet
Change 1/4 to 2/8 and then add. the answer is 7 7/8.
We write the expression:
((2 ^ (1/2)) * (2 ^ (3/4))) ^ 2
We use for this case the properties of lso exponents:
((2 ^ (1/2)) * (2 ^ (3/4))) ^ 2
((2 ^ (2/2)) * (2 ^ (6/4)))
((2 ^ (1)) * (2 ^ (3/2)))
((2 ^ (1 + 3/2))
((2 ^ (5/2))
answer:
((2 ^ (5/2))
option 2
There were 215 students in soccer class.
Step-by-step explanation:
Given,
Number of students in tennis class = 129
2/3 of tennis class students = 
2/3 of tennis class students = 86
Number of soccer students = Number of tennis students + 2/3 of tennis students
Number of soccer students = 129+86
Number of soccer students = 215
There were 215 students in soccer class.
