Based on the distance formula, the distance between points (3, 7) and (x1, y) is: \sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}. SO, it is TRUE.

<h3>What is the Distance Formula?</h3>

The distance formula which can be applied to find the distance between two coordinate points is: d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}.

Given the points:

(x1, y1)

(3, 7) = (x2, y2)

Substitute

d = \sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}

Therefore, the statement that says the distance between points (3, 7) and (x1, y) = \sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}, is TRUE.

∠1 ​ and ∠2 are supplementary. ∠1=124°∠2=(2x+4)° Select from the drop down menu to correctly answer the question.
Alex_Xolod [135]
Remark
Supplementary angles add up to 180o. 

Givens
<1 = 124
<2 = 2x + 4

I imagine you are looking for either x or <2. 

Equation
<1 + <2 = 180          Substitute the givens
124 + 2x + 4 = 180  Collect like terms on the left.
128 + 2x = 180         Subtract 128 from both sides
2x = 180 - 128          Collect like terms on the right   
2x = 52                     divide by 2
x = 52/2
x = 26 <<<<<<<<< answer

<1 = 124
<2 = 2x + 4 = 2*26 + 4
<2 = 52 + 4
<2 = 56  <<<<<<<< answer

We need choices if you want an exact answer.
