Answer:
A=10 cm
B=5 cm
Area of square = 25 cm
Step-by-step explanation:
Since that is an equilateral triangle based off the fact that all the sides are the same variable (a) then that means 30 divided by 3 which equals 10. So now we know that a = 10. Lets input that information for the rectangle. Since there are 2 a's that equals 20 and the perimeter is 30 so b has to be 5 since 5 times 2 is 10 plus 20 equals 30. so now we know that a=10 and b=5 so our squares sides are all 5. The area of the square is 25
Trapezoid
even if its tilt, if you put it down, its a trapezoid
It should be b but i don’t have paper with me so i’m not sure

Answer:
2^(1 + ((n-1) mod 4)) mod 10
Step-by-step explanation:
We presume you want the last digit of the power of 2, not the last digit of the exponent. Powers of 2 mod 10 are ...
2^0 : 1
2^1 : 2
2^2 : 4
2^3 : 8
2^4 : 6
2^5 : 2 . . . . and the sequence repeats: 2, 4, 8, 6, ...
That is, ...
(2^n) mod 10 = 2^(1 + ((n-1) mod 4)) mod 10 . . . for n > 0
