Answer:
180 degrees.
Step-by-step explanation:
Because the angle at the circumference is 90 degrees the arc joining the 2 other points = 180 degrees.
So x = 360 - 180 = 180 degrees.
For this case we have to represent the following expression algebraically:
"10 less than x is -45"
So:
10 less than x is represented as: 
Then, the complete expression is represented as:
Adding 10 to both sides of the equation:
Thus, the value of the variable is 
Answer:
Answer:
c. (5, -2)
Step-by-step explanation:
as we can clearly see, the 4th vertex has to be on the positive side of x.
therefore, all answer options with negative x are out.
(2, -5) is almost at D (-1, 5). that cannot be right for a rectangle.
that leaves only c as right answer.
FYI - how to get this without predefined answer portions ?
the x- difference of B to A is 4 (from -5 to -1). the x-difference from D to C must be the same (4). 1 + 4 = 5.
so, x of D must be 5.
the y- difference of B to A is 3 (from 3 to 6). the y-difference from D to C must be the same (3). -5 + 3 = -2.
so, y of D must be -2.
50 = 2 x 25 = 2 x 5 x 5 = 2 x 5^2
20 = 2 x 10 = 2 x 2 x 5 = 2^2 x 5
