Answer:
you mean 360 mall :)
Step-by-step explanation:
A number is rational if it can be written in form a/b where a and b are integers and b is not equal to 0
integers are like -4,-3,-2,-1,0,1,2,3,4, etc
so
√20=2√5 which is irrational because we can't write it as a fraciton with only integers
also a rational number multilied by an irratinonal number=irrtaional
we know that the square root of any prime number will be irrational and 5 is prime so 2 times √5=rational times irrational=irrational
√20 is irrational
Answer: Sin R= 10.1
Cos R= 31.6
Tan R= 9.6
Sin T= 22.9
Cos T=37.7
Tan T= 10.9
Step-by-step explanation:
Third side is 39^2
A)
x = # of students in math class
2x+7=40
B)
2x+7=40
-7
------------
2x = 33
--- ---
2 2
x = 76 students
