Find the value of x. the diagram is not to scale.

opposite angles are equal so where the 110 is outside the triangle, it is also 110 inside the triangle.

 the 3 angles need to = 180

 so you have 110 + 57 = 167

x = 180-167 = 13

x = 13

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
