They give you the same answer it just that one has parenthesis and the other one doesn't.
What is the distance between (4, 7)(4,7)left parenthesis, 4, comma, 7, right parenthesis and (2, 2)(2,2)left parenthesis, 2, com

Answer: square root of 29
Step-by-step explanation:
Given the question :
Distance between (4, 7) and (2, 2)
Distance between two points is given by:
Distance = sqrt[(X2 - X1)² + (Y2 - Y1)²]
X1 = 4 ; Y1 = 7 ; X2 = 2 ; Y2 = 2
Distance = sqrt[(2 - 4)² + (2 - 7)²]
Distance = sqrt[(-2² + - 5²)]
= sqrt(4 + 25)
= sqrt(29)
Opposite angles of inscribed quadrilaterals are supplementary.
That means ∠D + ∠B = 180°
So, we can substitute in the given values.
(4x + 3) + (2x + 3) = 180
Solve for x.
4x + 3 + 2x + 3 = 180
6x + 6 = 180
6x = 174
x = 29
We know ∠C = 2x + 1, so we can substitute our value of x in.
∠C = 2x + 1
∠C = 2 * 29 + 1
∠C = 58 + 1
∠C = 59°
