Softa [21]

Answer:

x = 54, so the vertical angles are 110°.

Step-by-step explanation:

$2x + 2 = 3x - 52$

$2 = x - 52$

$x = 54$

$2(54) + 2 = 108 + 2 = 110$

$3(54) - 52 = 162 - 52 = 110$

Geometry question for homework.

mars1129 [50]

So remember that the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

$\sqrt{(4-4)^2+(-2-(-5))^2}\\ \sqrt{0^2+3^2}\\ \sqrt{0+9}\\ \sqrt{9}\\ 3$

Distance between (4,-5) and (4,-2) is 3 units.

$\sqrt{(1-(-1))^2+(1-4)^2}\\ \sqrt{2^2+(-3)^2}\\ \sqrt{4+9}\\ \sqrt{13}$

Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
