Question

Find the value of each variable​

Answer 1

y = 94

z = 77

Explanation:

Since the angle z is supplementary to 103, we can say that.

z + 103 = 180

Solving for z, we get that z = 77.

Now, to solve for y, we need to recall the fact that the internal angles in a quadrilateral always add up to 360. We know 3 of the angles, so we can set up an equation:

y+77+106+83 = 360

y+266 = 360

y = 94
