Answer:

$x\degree = 75\degree$

Step-by-step explanation:

Property used: <em>An exterior angle of a triangle is equal to the sum of the opposite interior angles.</em>

$= > 62\degree + (x + 13)\degree = 2x\degree \\ \\ = > 62\degree + x\degree + 13\degree = 2x\degree \\ \\ = > 75\degree = 2x\degree - x\degree \\ \\ = > 75\degree = x\degree \\ \\ = > x\degree = 75\degree$

W+3 3/8=1 5/6 what is the answer

Annette [7]

W + 3 3/8 = 1 5/6;

W = 1 5/6 - 3 3/8;

W = 11/6 - 27/8;

W = 11/(2*3) - 27/(2*4);

W = (11*4 - 27*3)/(2*3*4);

W = (44 - 81)/24;

W = -37/24 = -1 13/24;
