Find the value of x and y
Naddik [55]
Just a guess, but the angle inside the triangle that's not x or y is the remaining angle after subtracting the 30 degrees shown.  That makes the non labeled angle inside the triangle 150 degrees.  since all triangles are 180 degrees, this means x and y add up to 30.  They look roughly the same, so i'd guess they're both 15 degrees.

Please solve correctly<br> full explanation please<br> will give brainlist
rosijanka [135]

Answer:

They subtracted the values incorrectly

Step-by-step explanation:

The formula for finding the distance between two points is this:
\sqrt{} (x_{2} -x_{1})^{2}   + (y_{2} -y_{1} )^{2}

The person subtracted the variables incorrectly and subtracted x1 from x2 and y1 from y2 instead of the other way around.

To correctly solve it, do this:\sqrt{((-7-(-1))^2+(-6-2)^2} = \sqrt{(-6)^{2} + (-8)^{2}  } = \sqrt{36+64} = \sqrt{100} = 10

Hope this helped!
