Answer:

The answer to your question is 5.7

Step-by-step explanation:

Data

Point A = (2, 3)

Point B = (-2, 7)

Process

To find the distance between points A and B use the formula of the distance between two points, substitute and simplify.

Formula

dAB = $\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}$

-Identify wich is the value of x1, y1, x2, y2

x1 = 2 y1 = 3 x2 = -2 y2 = 7

-Substittion

dAB = $\sqrt{(-2 - 2)^{2} + (7 - 3)^{2}}$

-Simplification

dAB = $\sqrt{(-4)^{2} + (4)^{2}}$

dAB = $\sqrt{16 + 16}$

dAB = $\sqrt{32}$

-Result

dAB = 5.65 ≈ 5.7

in abc the measure of angle a is 2x+3, the measure of b is 4x+2, the measure of c is 2x-1. What are the measures of the angles?

Mama L [17]

The measures of the angles in a triangle add up to 180°.
$2x+3+4x+2+2x-1=180 \\
8x+4=180 \ \ \ |-4 \\
8x=176 \ \ \ |\div 8 \\
x=22 \\ \\
2x+3=2 \times 22+3=44+3=47 \\
4x+2=4 \times 22+2=88+2=90 \\
2x-1=2 \times 22-1=44-1=43$

The measures of the angles are 43°, 47° and 90°.
