Answer:
A.
Step-by-step explanation:
Perpendicular lines
area of square = 4ft²
a s area of square = length×lenght
let lenght =x
so area = x²
x²= 4ft²
taking square root
x=2 ftSo lebght of each side is 2 ft.
Expression 1 is the main equation and expression 2 is the more simplified equation from expression 1.
326 + 37g
-287 - 23g
-----------------
38 + 14g
(Though I think 38 is suppose to be 39.)
Answer:
x=45°
Step-by-step explanation:
A straight line is 180°. Since we have a 90° angle, and CD is a straight line, 90/2=45
45° is the answer.
