Step-by-step explanation:
substitute the letters with numbers and solve:
E=IR
12=I 3
12/3=4
Answer:
The correct option is a.
Step-by-step explanation:
Given information:
Number of elements in set A = 4
Number of elements in set B = 3
We need to find n(A × B). It means we have to find the number of elements in set A × B.
If P and Q are two sets with elements m and n respectively, then the number of element in the set P × Q is m × n.



The value of n(A × B) is 12. Therefore the correct option is a.
We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
