Answer:

Step-by-step explanation:
you can use hypotenuse formula
45-45-90 isosceles right triangle
so, 45= x
x² + x² = 24²
2x² = 24²
x²= 24.12
x= 
or :
you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = 
cm
so ;

a= 
hope this helps ^-^
53 degrees
Because 180 - 90 ( right angle ) - 37 = 53
This type of sampling would be Random Sampling.
5x + 20
5(x) + 5(4)
5(x + 4)
