Check the picture below.
since we know that ABCF is a rectangle, then AB = FC, and FA = CB, meaning FA = 4 as you see there.
Answer:
c i think
Step-by-step explanation:
The 2x and 76 are opposite angles so they are equal.
2x = 76
x = 38 degrees
y and 76 are adjacent angles so y = 180 - 76
= 104 degrees
In equations like this, you could use PEMDAS- Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction in that order. Since there are no parentheses or exponents you can go to multiplication. Since x=9 and y=6, you multiply x(9) and y(6) to get 54. Now you can add since there is no division or subtraction involved. 54+ u(2) = 56. So u + xy = B. 56
